5 Natural Treatments for Anemia Symptoms

By

Anemia symptoms - Dr. Axe

Anemia, also known as anaemia, occurs when your blood has a lower than normal number of red blood cells or if your red blood cells don’t have enough hemoglobin. Because a side effect of anemia is low circulation of oxygen, anemia symptoms usually include muscle weakness, ongoing fatigue or lethargy, brain fog, and sometimes mood changes.

Severe anemia or unabated anemia can also sometimes cause complications, including damage to your heart, brain and other organs, according to the National Heart, Lung, and Blood Institute (NHLBI). Although it’s rare, anemia that remains untreated can even become deadly.

Considering the seriousness of anemia and how common it is among certain age groups — especially women during reproductive years or adults with existing health conditions who are over 65 — it’s imperative that you learn how to recognize anemia symptoms in yourself or your loved ones.

Below you’ll learn about the most common signs of anemia, as well as the best ways to treat anemia symptoms and reduce anemia risk factors, such as iron deficiency or eating a highly processed diet.

What is anemia?

Anemia is the condition marked by a deficiency of red blood cells or of hemoglobin in the blood.

Hemoglobin is an iron-rich protein that gives your blood its red color. It helps cells bring oxygen from your lungs to the rest of your body.

If you have anemia, your body simply doesn’t receive enough oxygen-rich blood, leaving you tired and weak.

Red blood cells contain hemoglobin. They are also important for immunity, including fighting infections, as well as clotting blood and preventing too much bleeding.

Anemia is closely related to iron deficiency. According to the Centers for Disease Control and Prevention (CDC), iron deficiency is the most common nutritional deficiency in the world.

This is alarming considering the essential roles that iron plays, including facilitating oxygen distribution. Your body needs iron to perform many functions throughout every single day, but it’s common for many people to live with low iron levels due to factors like blood loss (such as from menstruation), a poor diet or an inability to absorb enough iron from food sources.

Anemia symptoms

Without enough oxygen-carrying red blood cells in your body, it’s impossible to transport adequate amounts of oxygen to your brain, tissues, muscles and cells.

Feeling a little “out of it” and tired is pretty common for many adults due to compounding reasons. These can include stress, lack of sleep, battling a virus and a busy work schedule, among others.

Therefore, when it comes to knowing whether or not you should be checked for anemia, it’s important to understand how anemia symptoms usually manifest and what makes them different than simply feeling exhausted due to other life circumstances.

Here are some of the most common anemia symptoms adults tend to experience:

  • Fatigue
  • Weakness
  • Pale skin
  • A fast or irregular heartbeat
  • Shortness of breath, trouble breathing, low stamina and reduced endurance
  • Chest pains
  • Dizziness or loss of stability
  • Cognitive problems, including brain fog, difficulty concentrating and trouble getting work done
  • Cold hands and feet or other signs of body temperature changes
  • Headaches

You should also be aware that, initially, anemia can be so mild that it often goes unnoticed for a period of time, sometimes even for years. But anemia symptoms typically worsen as the condition progresses, especially if more than one risk factor is contributing to the problem.

You can find out if you have low red blood cells by taking a hematocrit test, along with a hemoglobin test.

What is anemia + natural treatments

Types

Here are the main types of anemia along with their causes and symptoms:

1. Iron deficiency anemia

The most common type of anemia, iron deficiency anemia is exactly what it sounds like: anemia caused by low iron levels.

Causes:

  • Inadequate dietary intake of iron
  • Chronic blood loss (e.g., from heavy menstruation or gastrointestinal bleeding)
  • Inability to absorb iron (due to conditions like celiac disease or after certain surgeries)
  • Pregnancy

Iron deficiency anemia symptoms:

  • Fatigue and weakness
  • Pale skin
  • Shortness of breath
  • Dizziness or lightheadedness
  • Cold hands and feet
  • Brittle nails
  • Headache

2. Vitamin B12 deficiency or folate deficiency anemia

Also known as cobalamin deficiency, vitamin B12 deficiency anemia occurs when the body can’t make enough red blood cells due to a B12 deficiency. Folate deficiency anemia is basically the same thing but due to a folate deficiency.

Causes:

  • Poor dietary intake of vitamin B12 or folate
  • Malabsorption disorders (e.g., pernicious anemia, celiac disease)
  • Certain medications (e.g., anticonvulsants, proton pump inhibitors)
  • Pregnancy

B vitamin deficiency anemia symptoms:

  • Fatigue and weakness
  • Pale or jaundiced skin
  • Shortness of breath
  • Dizziness or lightheadedness
  • Numbness or tingling in hands and feet
  • Memory loss or cognitive difficulties
  • Glossitis (swollen, red tongue)

3. Anemia of chronic disease

According to the National Institute of Diabetes and Digestive and Kidney Diseases, “Anemia of inflammation is also called anemia of chronic disease because this type of anemia commonly occurs in people who have chronic conditions that may be associated with inflammation.”

Causes:

  • Chronic infections (e.g., tuberculosis)
  • Chronic inflammatory diseases (e.g., rheumatoid arthritis, lupus)
  • Chronic kidney disease
  • Cancer

Anemia of inflammation symptoms:

  • Fatigue and weakness
  • Pale skin
  • Shortness of breath
  • Dizziness or lightheadedness
  • Symptoms related to the underlying chronic disease

4. Aplastic anemia

Also known as bone marrow failure, aplastic anemia “is a rare but serious blood condition that occurs when your bone marrow cannot make enough new blood cells for your body to work normally.”

Causes:

  • Autoimmune diseases
  • Exposure to toxic chemicals (e.g., pesticides, benzene)
  • Radiation and chemotherapy
  • Certain medications (e.g., antibiotics, anticonvulsants)
  • Viral infections (e.g., hepatitis, HIV)

Aplastic anemia symptoms:

  • Fatigue and weakness
  • Pale skin
  • Shortness of breath
  • Dizziness or lightheadedness
  • Frequent or prolonged infections
  • Easy bruising and bleeding
  • Nosebleeds and bleeding gums

5. Hemolytic anemia

When your red blood cells are destroyed faster than they can be replaced, it’s called hemolytic anemia, which is its own blood condition.

Causes:

  • Autoimmune disorders (e.g., autoimmune hemolytic anemia)
  • Genetic disorders (e.g., sickle cell anemia, thalassemia)
  • Infections
  • Certain medications (e.g., penicillin, antimalarial drugs)
  • Blood transfusion reactions

Hemolytic anemia symptoms:

  • Fatigue and weakness
  • Pale or jaundiced skin
  • Shortness of breath
  • Dizziness or lightheadedness
  • Dark-colored urine
  • Enlarged spleen
  • Rapid heart rate

6. Sickle cell anemia

This lifelong disease “is a group of inherited red blood cell disorders that affect hemoglobin.”

When you have sickle cell disease, “red blood cells become crescent- or ‘sickle’-shaped due to a genetic mutation. These sickled red blood cells do not bend or move easily and can block blood flow to the rest of the body.”

Causes:

  • Genetic mutation (inherited condition)

Sickle cell anemia symptoms:

  • Episodes of pain (sickle cell crises)
  • Fatigue and weakness
  • Pale or jaundiced skin
  • Shortness of breath
  • Dizziness or lightheadedness
  • Swelling in the hands and feet
  • Frequent infections
  • Delayed growth and development in children

7. Thalassemia

According to the National Institutes of Health, “Thalassemia is a heterogeneous group of blood disorders affecting the hemoglobin genes and resulting in ineffective erythropoiesis. The decreased production of hemoglobin results in anemia in early age and frequent blood transfusions are required to keep up the hemoglobin levels.”

Causes:

  • Genetic mutation (inherited condition)

Thalassemia symptoms:

  • Fatigue and weakness
  • Pale or jaundiced skin
  • Shortness of breath
  • Dizziness or lightheadedness
  • Facial bone deformities
  • Slow growth
  • Abdominal swelling (due to enlarged spleen or liver)
  • Dark urine

8. Pernicious anemia

Pernicious anemia “is a relatively rare autoimmune disorder that causes diminishment in dietary vitamin B12 absorption, resulting in B12 deficiency and subsequent megaloblastic anemia.”

Causes:

  • Autoimmune condition that affects the absorption of vitamin B12

Pernicious anemia symptoms:

  • Fatigue and weakness
  • Pale or jaundiced skin
  • Shortness of breath
  • Dizziness or lightheadedness
  • Numbness or tingling in hands and feet
  • Memory loss or cognitive difficulties
  • Glossitis (swollen, red tongue)

Each type of anemia has unique causes and symptoms, but fatigue and weakness are common across all types due to the reduced oxygen-carrying capacity of the blood.

Causes and risk factors

There are three primary reasons why you might develop anemia from not having enough red blood cells:

  • You’re not producing enough red blood cells.
  • You’ve been losing too much blood due to injury, menstruation or other circumstances that cause bleeding.
  • Your body is destroying the red blood cells you have due to changes in your immune system.
  • Deficiency in iron or vitamin B12. This can happen if you don’t eat enough in general, you eat a restrictive diet or sometimes if you’re a vegetarian/vegan who avoids animal products (since these are good sources of iron and B vitamins). Your body needs adequate iron, vitamin 12, folate and other nutrients from the foods you eat in order to produce healthy amounts of hemoglobin and red blood cells.
  • Being a woman, since women develop anemia more often than men do.
  • In people who have pernicious anemia, they are getting enough vitamin B12 but aren’t able to properly metabolize or use it. Because of this, their bodies still can’t make enough hemoglobin.
  • Older age. Research shows people over 65 are more likely to develop anemia.
  • Pregnancy can also increase risk for anemia.
  • Candida, which can alter how you absorb nutrients, including B vitamins.
  • Other conditions, including an autoimmune disease (like lupus, for example), HIV/AIDS, rheumatoid arthritis, kidney disease or cancer can cause anemia. If you have kidney issues and anemia, your erythropoietin — a glycoprotein that controls red blood cell production — may be off. If your kidneys don’t produce enough of it, it can contribute to anemia.
  • Having a digestive issue that disrupts nutrient absorption, such as inflammatory bowel disease, Crohn’s disease or an ulcer.
  • Frequently taking over-the-counter pain relievers, especially aspirin, which block certain nutrients.
  • Sometimes anemia is genetically inherited and therefore less likely to be due to lifestyle factors or your diet. These include aplastic anemia (your body doesn’t produce enough red blood cells), bone marrow diseases like leukemia and myelofibrosis, hemolytic anemia (red blood cells are destroyed faster than bone marrow can replace them), or sickle cell anemia (having a defective form of hemoglobin that produce red blood cells that can’t be used and causes blood cells to die prematurely). A genetic disorder called G6PD deficiency may also contribute to anemia.
  • Thalassemia is another condition that can lead to anemia. This inherited blood disorder marked by fewer red blood cells and less hemoglobin in the body than normal, which can cause anemia.

How diet affects anemia

Aside from getting enough iron and B vitamins (more on this below), what’s one of the most important things you can do to overcome anemia? Remove ultra-processed and junk foods from your diet as much as possible.

Consuming lots of empty calories — like ultra-processed and junk foods, such refined grains, fast food, synthetic ingredients or excess sugar, for example — can contribute to deficiencies in essential nutrients, fatigue, weight gain, weakness, and also inflammatory bowel disease (IBD) or candida. 

Candida is a condition that results in high levels of yeast proliferating and disturbing the normal pH balance and mucous lining of the gastrointestinal tract. This causes changes how you absorb nutrients.

Oftentimes, digestive issues, like IBD or candida, and anemia are linked, especially in women. If you ever notice a white color on your tongue or in the back of your throat, or if you ever tend to get any sort of yeast issues, these are signs of candida symptoms.

Along with digestive issues and chronic fatigue, brain fog is often overlooked as a sign of candida and IBD. IBD or candida overgrowth can cause a lack of focus, poor physical coordination, difficulty in concentrating on tasks and poor memory, just like anemia can.

In order to overcome candida and related digestive issues, it’s usually very helpful to try eliminating almost all ultra-processed sugars and grains at least for a period of time. In other words, trying an “elimination diet” might greatly help control anemia symptoms.

If you are eating a lot of sugary foods, pastas, breads, cereals or really any type of refined grain product or sweetener, they’re going to feed yeast in your GI tract. This can block iron absorption and worsen anemia, so addressing the quality of your diet is key for recovery.

I recommend replacing these problematic, low-nutrient foods with things like fresh veggies, lean protein and healthy fats. This will help restore digestive/gut health and also provide you essential nutrients, including iron.

Here Are the Worst Foods for Anemia to Avoid:

  • Added sugar/sweeteners
  • Processed grains
  • Dark chocolate. Although chocolate is rich in iron, it also contains tannins, a type of antinutrient that interferes with iron absorption. Keep intake in moderation, include plenty of other iron-rich foods in your diet, and stick to milk and white chocolate varieties to minimize tannin intake.
  • Bran. Bran is high in insoluble fiber that traps and removes iron during digestion.
  • Conventional dairy. Calcium binds with iron in foods and can lead to poor absorption.
  • Soda. Soda is high in sugar and poor in nutrients, and it blocks iron absorption.
  • Coffee and black tea. Excessive coffee intake may block iron absorption, so reduce it to no more than one cup per day.

Natural treatments

You can treat anemia symptoms naturally in the following ways:

1. Nourish your spleen

The first natural treatment for anemia is really nourishing your spleen.

Your spleen is an organ that is responsible for red blood cell production, as well as keeping fluids together in your system. If your spleen isn’t healthy, that’s one of the first factors that’s going to cause anemia.

There are specific foods that will actually help nourish your spleen, helping you overcome anemia symptoms naturally.

That first food group is squash, specifically pumpkin, acorn squash, butternut squash, spaghetti squash and those bright orange-colored foods. Think fall harvest!

Those sorts of foods are fantastic for nourishing the spleen. Aim for getting one to two servings of squash in your daily diet.

If you want some ideas, try this Butternut Squash Soup as a starter.

The other food group that’s very important for nourishing your spleen and red blood cell production is green leafy vegetables, like nutrition-rich spinach, kale and chard. Having one serving of those per day, something like a Kale Caesar Salad or sautéed spinach, is also very nourishing to your spleen.

Last but not least, bitter foods are great for the spleen, specifically vegetables like romaine lettuce and arugula salad. You can even consume bitter herbs before a meal as a supplement, but anything that’s sort of a bitter food is very nourishing for the spleen.

2. Use probiotics for a healthy gut

Step No. 2 to help you naturally overcome anemia symptoms is to boost gut health with probiotics. Gut health is crucial for absorption of nutrients.

The principle is not: “You are what you eat.” Rather, it is: “You are what you digest.”

If you’re not digesting properly and absorbing and assimilating nutrients properly, you’re not absorbing iron!

For a lot of people taking iron supplements, unfortunately they might not be working all that well. The reason is that their digestive systems aren’t healthy.

They probably have a condition called leaky gut syndrome. Leaky gut doesn’t allow you to properly absorb iron as well as certain other vitamins and minerals, like vitamin B12, magnesium and zinc.

A medical study out of Stanford found that when somebody supplements with probiotics, all of that person’s B vitamin levels tend to go up, along with iron levels. So rather than simply popping an iron tablet without fixing the underlying problem, try to make changes that tackle the root problem of poor gut health.

I recommend you add in probiotic-rich foods to your diet, like real homemade yogurt, goat milk kefir and sauerkraut. Then taking a probiotic supplement can definitely help support your iron absorption.

3. Consume iron-rich foods

The next step in helping you overcome anemia symptoms is consuming iron-rich foods. The richest sources of heme iron (the more absorbable form) in the diet include lean meat and seafood.

Dietary sources of non-heme iron include nuts, beans, vegetables and fortified grain products. In the United States, about half of dietary iron comes from bread, cereal and other grain products, but I recommend focusing on healthier options that are easier to digest instead.

Some of the best iron foods include beef liver and chicken liver.

Liver? It might sound gross to you, but if you buy organic chicken liver at your local farmers market or at your health food store, you can put it in a slow cooker with chicken in equal ratios, or about a third liver, two-thirds chicken. Include vegetables like carrots, celery, onions and sea salt.

This is the perfect meal to help replenish your liver, as it’s very high in iron. 

For other iron-rich foods, look toward organic, grass-fed meats, like beef, bison and lamb. Also, eat spinach, kale and chard.

Have a bison burger with a side of spinach, which is fantastic for helping you to reverse anemia.

4. Reduce stress

If you’re emotionally stressed out and you struggle with forgiveness, anger, or have chronic worry and anxiety, those things really deplete your spleen and your liver and will exhaust those organs. So, really make sure that you are scheduling in times of relaxation and fun during your week.

Plus, get plenty of sleep at night.

Those things will really help recharge your system and body and help you relieve stress. If you do those things, you’re going to see fantastic results in overcoming anemia.

5. Consider taking supplements

In addition to making the holistic changes described above, you can likely benefit from taking a B vitamin complex supplement that includes folate (not folic acid!), as well as an iron supplement, according to the NHLBI.

Another bonus tip related to stress and spleen health: In Chinese medicine, anemia is very closely related to the spleen, and certain herbs actually help support the spleen, especially ginseng.

Ginseng is known as an adaptogenic herb that lowers cortisol. It can help your body better deal with stress.

Lastly, benefit-rich beets also help with a healthy circulatory system and healthy iron levels.

Diet to help reduce anemia

Even though anemia is so common, it’s possible for most healthy people without serious illnesses to prevent anemia by eating a healthy, unprocessed diet.

Above you read about foods to avoid in order to manage anemia symptoms and also candida. Now here are some of the best foods to include in your diet in order to overcome anemia:

  • Liver: Beef liver is very high in iron and vitamin B12 and a variety of other important minerals. If unable to consume cow liver, make sure you include grass-fed, organic beef as an alternative.
  • Brewer’s yeast: High in folic acid, vitamin 12 and iron. Add to cereal, salad or juice.
  • Foods high in vitamin C: Vitamin C helps with iron absorption. If you are eating a high-iron food (beef), try to include a source of vitamin C at that same meal, such as tomatoes, peppers or strawberries.
  • Green leafy vegetables: These provide a significant amount of iron and folic acid. Raw spinach is high in oxalic acid, which can reduce iron absorption — however, steaming spinach will reduce this acid. Other green leafy vegetables to include are steamed kale and broccoli.
  • Natural sweeteners (in small amounts): If you’re wondering what to do when you need to use some sort of sweetener but are avoiding added sugar, try blackstrap molasses or raw local honey in small amounts (about one tablespoon at most at a time). Blackstrap molasses can be taken in servings of about one spoonful daily, as it is very high in iron. Local honey or stevia are two other good options in terms of keeping too much sugar out of your diet but lightly sweetening foods.

Frequently asked questions

Can a person live a long life with anemia?

Yes, a person can live a long life with anemia, especially if it’s mild or well-managed. However, untreated or severe anemia can lead to complications over time, such as heart problems, which may affect longevity.

Can a person tell if he is anemic from his eyes?

Sometimes. Pale or light-colored inner eyelids (conjunctiva) may indicate anemia due to low hemoglobin.

However, this is not a definitive sign and should be confirmed with a blood test.

How can a person treat anemia herself?

Depending on the type of anemia, a person can increase her iron intake through foods like red meat, spinach and beans or take iron supplements. Vitamin C-rich foods can enhance iron absorption.

Folate and B12 supplements may also be beneficial for some forms of anemia.

Is anemia a permanent condition?

Anemia can be temporary or chronic, depending on its cause. Nutritional anemia (iron, folate or B12 deficiency) is typically reversible with proper treatment, while chronic conditions like anemia of chronic disease may persist.

How fast does anemia go away?

It depends on the severity and cause. With proper treatment, iron deficiency anemia can improve within a few weeks, but it may take two to three months to fully correct low iron levels.

How will I feel if my iron is low?

If your iron is low, you may feel fatigued, weak, have shortness of breath, headaches, dizziness, pale skin or experience heart palpitations.

How can I increase my iron level quickly?

Eating iron-rich foods (like red meat, poultry, beans and fortified cereals) along with foods high in vitamin C (like oranges or bell peppers) can help. Iron supplements, under medical supervision, can also raise levels quickly.

What causes iron levels to drop?

Iron levels can drop due to blood loss (from heavy periods, injuries or internal bleeding), poor dietary intake of iron or problems absorbing iron (due to conditions like celiac disease or inflammatory bowel disease).

Why would a person be anemic?

Anemia can be caused by iron deficiency, vitamin B12 or folate deficiency, chronic diseases (like kidney disease or cancer), genetic conditions (such as sickle cell anemia), or blood loss.

How do you fix anemia?

Treatment depends on the type. Iron deficiency anemia is treated with iron supplements and diet changes.

Vitamin deficiency anemia is treated with B12 or folate supplements. In cases of chronic disease, treating the underlying condition can improve anemia.

What are 5 symptoms of anemia?

  1. Fatigue
  2. Weakness
  3. Pale or yellowish skin
  4. Shortness of breath
  5. Dizziness or lightheadedness

What will happen if you are anemic?

If you are anemic, your body won’t get enough oxygen-rich blood, leading to fatigue, weakness and potential complications like heart problems if left untreated.

How do you feel when you are anemic?

Anemia can make you feel extremely tired, weak, short of breath, dizzy or faint. You may also feel cold, have headaches or experience difficulty concentrating.

What is anemia caused by?

Anemia is caused by a deficiency in red blood cells or hemoglobin. This can result from iron, folate or vitamin B12 deficiency; chronic disease; blood loss; or inherited conditions like sickle cell disease.

What happens if anemia goes untreated?

Untreated anemia can lead to serious complications, including heart problems (like an enlarged heart or heart failure), severe fatigue and organ damage due to insufficient oxygen delivery to tissues.

Precautions

Although you might be able to treat anemia on your own by making changes to your diet, lifestyle and the supplements you take, it’s also a good idea to talk with your doctor if you suspect you have anemia, considering it can be a side effect of other serious illnesses.

You might be exhausted and finding it hard to concentrate for other reasons that have nothing to do with anemia so don’t necessarily assume you’ve diagnosed yourself accurately.

If anemia symptoms persist after you’ve made the changes above, be sure to get tested for nutrient deficiencies, and get a doctor’s opinion.

Final Thoughts

  • Anemia, aka anaemia, is a common condition that occurs when your blood has a lower than normal number of red blood cells or if your red blood cells don’t produce enough hemoglobin, according to the National Heart, Lung, and Blood Institute.
  • Anemia caused by this hemoglobin deficiency lead to anemia symptoms that include brain fog, fatigue, weakness, trouble breathing normally, headaches and body temperature changes.
  • Anemia treated through these natural means can help reduce anemia symptoms and address underlying causes: Nourish your spleen. Use probiotics for a healthy gut. Consume iron-rich foods. Reduce stress. Consider taking supplements, such as a B complex vitamin and iron.
