Before discussing how to increase the hemoglobin level in our blood, it’s necessary to first talk about the importance of hemoglobin.
Hemoglobin is an important component of the circulatory system and plays an important role in maintaining overall health. It is a complex protein found in red blood cells (RBCs) and is essential for various physiological functions within the body.
Oxygen transport:
The main function of hemoglobin is to bind oxygen in the lungs and transport it throughout the body through the blood.
This oxygenated hemoglobin, called oxyhemoglobin, delivers oxygen to the tissues and organs that need it, ensuring that they function optimally.
Adequate oxygen transport is essential for cellular respiration, energy production, and survival of all body cells.
Removal of carbon dioxide:
Hemoglobin also helps remove carbon dioxide, a waste product of metabolism, from tissues.
As blood containing carbon dioxide returns to the lungs, hemoglobin picks up the carbon dioxide and carries it to the lungs for exhalation.
This process helps maintain the body’s acid-base balance and prevents the accumulation of toxic carbon dioxide.
pH regulation:
Hemoglobin acts as a buffer, helping to regulate blood pH by binding to excess hydrogen ions (H+).
This buffering capacity helps prevent changes in blood pH, ensuring that enzymatic reactions and other biochemical processes can occur within the body’s optimal pH range.
Diagnosis of medical conditions:
Hemoglobin levels are commonly used to diagnose and monitor various medical conditions.
Abnormal hemoglobin levels may indicate anemia, a condition characterized by a lack of RBCs or hemoglobin, or other underlying health problems.
Elevated hemoglobin levels can be associated with conditions such as polycythemia, which can have serious health implications.
Overall health indicator:
Hemoglobin levels are a reflection of a person’s overall health and nutritional status.
It is very important to maintain optimum level of hemoglobin to avoid anemia, fatigue, weakness.
Health implications of low hemoglobin levels:
Fatigue and weakness:The primary function of hemoglobin is to carry oxygen to tissues and organs. When hemoglobin levels are low, the body does not get an adequate supply of oxygen, leading to fatigue and weakness. People with anemia often feel tired even after minimal physical activity.
2. Shortness of breath:
Inadequate delivery of oxygen to body tissues can result in shortness of breath, especially during exertion. People with anemia may find it difficult to perform normal activities without feeling short of breath.
3. Light skin and nail beds:
Hemoglobin gives blood its red color, and low levels can cause yellowing of the skin and nail beds. It is one of the most visible signs of anemia and often appears on the face, hands and other exposed areas.
4. Cold hands and feet:
Inadequate oxygen can cause poor blood circulation, causing cold hands and feet. Cold is the result of the body prioritizing oxygen delivery from peripheral areas to more vital organs.
5. Dizziness and light-headedness
Insufficient oxygen reaching the brain can cause dizziness and light-headedness. People with anemia may feel dizzy upon standing up quickly or standing for long periods of time.
6. Headache:
Low hemoglobin levels can contribute to headaches due to reduced oxygen supply to the brain. Persistent or recurring headaches may be a sign of chronic anemia.
7. Irregular heartbeat:
The heart compensates for low oxygen levels by pumping more blood, which can cause an irregular heartbeat. Over time, this increased workload on the heart can contribute to cardiovascular problems.
8. Impaired Cognitive Function:
Inadequate oxygenation can affect cognitive function, resulting in difficulty concentrating, memory problems, and decreased mental alertness.
9. Weak Immune System:
Anemia can compromise the immune system, making individuals more susceptible to infections and delaying the recovery process from illnesses.
10. Increased risk during pregnancy:
Low levels of hemoglobin in pregnant women (a condition called iron deficiency anemia) can increase the risk of premature birth, low birth weight, and growth problems in the newborn.
11. Effect on Exercise Performance:
Athletes with anemia may experience slower recovery time due to reduced endurance, reduced exercise tolerance, and decreased oxygen-carrying capacity of the blood.
12. Basic Health Conditions:
Chronically low hemoglobin levels may indicate underlying health conditions such as nutritional deficiencies (iron, vitamin B12, folic acid), chronic kidney disease, gastrointestinal bleeding, or bone marrow disorders.
Diagnostic tests to measure hemoglobin levels
Accurate measurement of hemoglobin levels is essential for diagnosing anemia and monitoring the effectiveness of treatment. Various diagnostic tests are available to estimate the level of hemoglobin in the blood. Here is a brief note that outlines some of the common diagnostic tests used to measure hemoglobin levels:
Complete Blood Count (CBC): CBC is one of the most common and comprehensive tests used to measure hemoglobin levels. It provides information about red blood cell count, hemoglobin concentration, hematocrit (percentage of blood containing red blood cells) and other relevant parameters. This test is done by taking a blood sample and analyzing it in a laboratory.
Hemoglobin A1c (HbA1c) test: The HbA1c test measures the average level of glucose in the blood over the past 2-3 months. Although it is primarily used to monitor diabetes, it indirectly reflects hemoglobin levels because glucose binds to hemoglobin in red blood cells. An elevated HbA1c level may suggest anemia if other causes of high blood sugar are ruled out.
Fingerstick Hemoglobin Test: This point-of-care test is often used in clinical settings to provide a rapid assessment of hemoglobin levels. A small drop of blood from the finger is placed on the testing strip, which is then injected into a handheld device for instant results. This is an easy and quick way to screen for anemia.
Hematocrit test: Hematocrit measures the percentage of red blood cells in the total blood volume. Although it does not directly measure hemoglobin levels, it correlates closely with them. A low hematocrit level often indicates anemia.
Peripheral blood smear: In this test, a thin layer of blood is spread on a glass slide, stained and examined under a microscope. It allows healthcare providers to visually assess the size, shape and appearance of red blood cells, helping to identify specific types of anemia and other blood disorders. .
Serum Ferritin Test: Serum ferritin levels provide information about the body’s iron stores. Because iron is an essential component of hemoglobin, low serum ferritin levels may indicate iron deficiency anemia, a common type of anemia.
Erythropoietin (EPO) test: EPO is a hormone produced by the kidneys that stimulates the production of red blood cells. Measuring EPO levels can help determine whether anemia is due to insufficient production of EPO, which can occur in certain kidney diseases.
Bone marrow biopsy: In cases where other tests are inconclusive or when a specific type of anemia is suspected, a bone marrow biopsy may be done. This involves removing a small sample of bone marrow from the hip bone and examining it under a microscope to assess red blood cell production.
These diagnostic tests help health care providers identify the underlying cause of anemia and determine the most appropriate treatment. Depending on the results, treatment may include dietary changes, iron supplements, vitamin B12 or folate supplements, or addressing other underlying medical conditions contributing to low hemoglobin levels. Regular monitoring of hemoglobin levels is essential to track progress and ensure treatment effectiveness.
How to increase hemoglobin level.
Diet and lifestyle changes are often required to increase hemoglobin levels in the blood. Red blood cells contain a protein called hemoglobin, which carries oxygen throughout your body. Anemia, which can cause fatigue, weakness and other health problems, is the result of low hemoglobin levels. Here are some strategies to increase hemoglobin levels:
Iron rich diet:
Hemoglobin is mostly made up of iron. Include iron-rich foods in your diet, such as spinach, kale, red meat, chicken, fish, beans, lentils, tofu, and whole grains.
Vitamin C:
Vitamin C improves your body’s ability to absorb iron. Add items like bell peppers, oranges, strawberries and kiwi to your diet.
Folate (folic acid):
The formation of red blood cells depends on folic acid (folate).
Leafy vegetables, citrus fruits, legumes, and fortified cereals are some of the foods that are high in folate.
Vitamin B12:
The production of red blood cells depends on this vitamin. Meat, fish, eggs and dairy products are its main sources. If you are vegetarian or vegan, consider taking a B12 supplement.
Copper:
Copper plays a role in how iron is metabolized. Organ meats, whole grains, nuts and seeds are foods high in copper.
Avoid iron blockers:
Some foods and drinks can block iron absorption. These include calcium rich foods, tea and coffee. Avoid eating them before or immediately after meals that are high in iron.
Cast Iron Cooking:
Using cast iron cookware can increase the iron content of your food.
Stay hydrated:
If you’re dehydrated, your blood can become more concentrated, which can affect hemoglobin levels. Make sure you are getting adequate water.
Exercise frequently:
Regular exercise can stimulate the formation of red blood cells.
To manage chronic diseases:
Work with your healthcare professional to treat any underlying medical conditions you may have, such as chronic kidney disease or inflammatory diseases. Hemoglobin levels can be affected by several conditions.
Avoid smoking and consumption of alcohol:
These behaviors can cause low hemoglobin levels. If you drink, do so in moderation or avoid doing so.
If you smoke, consider quitting.
Get enough sleep:
Getting enough sleep is essential for overall health and can help with natural body processes, such as the formation of red blood cells.
Consult a doctor:
Consult a healthcare professional if your hemoglobin level remains low despite diet and lifestyle changes. They can identify any underlying medical problems and prescribe appropriate treatment.
Remember that it may take some time to see a significant increase in hemoglobin levels, and individual needs vary. Always consult a health care provider before making significant changes to your diet or taking supplements, especially if you have existing health conditions. They may do blood tests to monitor your progress and provide personalized recommendations.
