How To Increase Hemoglobin In A Week? | Types Of Hemoglobin

Hemoglobin is a protein detected in red blood cells, and blood cells are responsible for carrying oxygen throughout the body.

In addition to carrying oxygen, hemoglobin takes carbon dioxide out of the cells and into the lungs. Carbon dioxide is later released as a person breathes. Having a low hemoglobin level can make it tough for the body to do these functions.

In this post, we learn about how to increase hemoglobin levels. We look at methods of testing and what the results show.

I have already shared a post related to this topic: Severe Anemia In Pregnancy. I hope you read this post.

Types of hemoglobin

Various types of hemoglobin may be tested to identify possible complications. The average hemoglobin is called Hemoglobin A1, or HbA1, and makes up 90% of the hemoglobin in the blood. Low levels of normal hemoglobin may indicate blood loss or anemia. In addition, there are some hundred abnormal types of hemoglobin; some tested types are discussed below.

Type of Hb



Hemoglobin Al

12.1-16.3 g/dL 9096 of total hemoglobin

Low level indicates anemia or blood loss.

Hemoglobin A2

1.596-3.5% of total hemoglobin

High levels may indicate thalassemia.

Hemoglobin F

50-90% in neonates. 03611% of total hemoglobin in adults

Normally high in neonates.long term elevations may indicate a thalassemia.

Hemoglobin S

Presence is abnormal

Indicative of sickle cell disease.



High levels may indicate a hemolytic amenia.

How to increase hemoglobin

A person increases their hemoglobin levels at home by:

Increasing iron intake

A person with reduced levels of hemoglobin can benefit from eating more iron-rich foods. This is because ironworks boost the production of hemoglobin, which also helps to form more red blood cells.

Iron-rich foods include:

  • Meat and fish
  • Soy products, including tofu and edamame
  • Broccoli
  • Eggs
  • Nuts and seeds
  • Green beans
  • Dried fruits
  • Green leafy vegetables
  • Peanut butter

Increasing folate intake

Folate is one type of vitamin B that plays a vital part in hemoglobin production. The human body uses folate to produce heme, a component of hemoglobin that helps to provide oxygen.

If a person does not get sufficient folate, their red blood cells will not mature, leading to folate-deficiency anemia.

Good sources of folate include:

  • Beef
  • Spinach
  • Rice
  • Peanuts
  • Black-eyed peas
  • Kidney beans
  • Avocadoes
  • Lettuce

Folate supplements are available for purchase online.

Maximizing iron absorption

Using iron in foods or supplements is great, but a person should help their body to absorb that iron.

Vitamin C-rich foods, such as leafy green vegetables, strawberries, and citrus fruits, can boost your iron absorption. Taking a vitamin C supplement also helps you increase hemoglobin.

Vitamin A and beta-carotene aid the body in absorbing and using iron.

For further info must read this post: Does Vitamin C Help With Covid?

Foods rich in vitamin A include:

  • Fish
  • Squash
  • Liver
  • Sweet potatoes
  • Kale and collards
  • Foods high in beta-carotene include squash red, yellow, and orange fruits and vegetables, such as:
  • Mangoes
  • Squash
  • Sweet potatoes
  • Carrots
  • Cantaloupes

Vitamin A supplements help the body process iron, and the vitamin is bad if too much is consumed.

Excess vitamin A can lead to a condition known as hypervitaminosis A. This can cause joint pain, severe headaches, and increased pressure within the brain.

Taking iron supplements

A doctor advises a person with low levels of hemoglobin to take iron supplements. The dosage depends on a person’s hemoglobin levels.

It is essential to note that too much iron can be dangerous for people. It can cause hemochromatosis, leading to liver disease and side effects such as constipation and vomiting.

Supplements cause levels of iron to increase over a few weeks. However, a doctor recommends taking the supplements for many months to increase the body’s iron stores.

Iron supplements are available for purchase online.

Normal ranges

A doctor will check your low hemoglobin with a blood test.

Low hemoglobin is treated when a man has less than 13.5 gm per deciliter (g/dL) of hemoglobin in the blood, or a woman has less than 12 g/dL.

A person becomes a low hemoglobin level for reasons including:

A doctor’s supervision can boost their hemoglobin levels to fall within a normal range with a doctor’s supervision. Normal ranges are:

  • For women:12 to 15.5 g/dL 
  • For men: 13.5 to 17.5 g/dL 

People with low hemoglobin levels can need further treatment if taking supplements and changing the diet do not show enough results.

Symptoms of very low levels of hemoglobin include:

  • Fatigue
  • A fast or irregular heartbeat
  • Pale skin and gums
  • Muscle weakness
  • Unexplained bruising
  • Headaches

Causes of low hemoglobin:

A person with very low hemoglobin has anemia. Common causes of anemia include:

Low hemoglobin levels can be caused by:

  • Burns
  • Excessive smoking
  • Lung disease
  • Extreme physical exercise


Several people can boost their hemoglobin levels with dietary changes and supplements. Speak with a doctor to determine the dosage of the right supplement.

If hemoglobin levels remain low, a person needs more treatment, such as a blood exchange.

It depends on the cause of low hemoglobin and its treatments, and it can take a year for levels to reach a normal range.
