Decreased hemoglobin. What to do? Causes.

To better understand what are the reasons for low hemoglobin in the blood. Let’s see how it is formed in our body. A complex combination of protein with iron in red blood cells (erythrocytes), hemoglobin, is involved in the transfer of oxygen molecules to tissues and organs throughout the body. In general, our body breathes due to hemoglobin.

In order for hemoglobin to form, certain conditions are necessary:

  • Get enough iron through food.
  • Absorption in the stomach and in the small intestine of iron.
  • Vitamins B – 12 and folic acid are absorbed in the upper gastrointestinal tract and affect the formation of red blood cells in the bone marrow of any person. When the number of red blood cells decreases, then the amount of hemoglobin also decreases.
  • Hereditary and acquired blood disease.


  • For men per liter of blood 130-160 grams.
  • For a woman 120 – 147 g / l.
  • For a pregnant woman, not less than 110 hl.

Causes of Hemoglobin Loss

Blood loss is obvious, this is when a woman’s menstruation is profuse and more than 5 days. This also includes bleeding during hemorrhoids, during operations. There are also hidden blood loss, with diseases of the gastrointestinal tract. Uterine fibroids, ovarian cysts, which sometimes fill with blood.

Pathology hereditary, infectious and autoimmune diseases lead to the destruction and shortening of the life of red blood cells.

Hemoglobin can fall with hormonal disorders.

The reason for low hemoglobin in children is poor nutrition, unbalanced in composition with vitamins and minerals.

Symptoms of low hemoglobin

  1. General weakness, drowsiness, fatigue, severe dizziness, headaches, low blood pressure, palpitations.
  2. With a lack of iron in organs and tissues, changes in the nail plates occur (they are brittle, thin and exfoliate). The skin is dry, the lips have a bluish appearance, the hair grows slowly or falls out. Taste and smell change (there is a strong, inexplicable desire to eat chalk, coal, etc.).
  3. The pale appearance of the patient is a lack of vitamin B – 12, the tongue is red and painful.
  4. The immune system suffers. Because of what, frequent illnesses.

The initial stage of iron deficiency anemia can occur without any symptoms.

What diseases cause low hemoglobin

  • Iron deficiency anemia (IDA) is a lack of dietary iron intake.
  • Violation of absorption in the gastrointestinal tract, vitamin B – 12 and iron.
  • Chronic gastritis, enteritis.
  • Haemorrhoids.
  • Rheumatoid arthritis, glomerulonephritis, lupus erythematosus and other vasculitis.
  • Prolonged dysentery, salmonellosis, pyelonephritis, tuberculosis, etc.
  • Invasions are helminthic, absorbing B – 12
  • Intestinal patency is very weak.
  • Iron deficiency occurs after burns, the appearance of pulmonary or cardiovascular insufficiency.
  • Neoplasms are malignant.

During the summer holidays, it is advisable to go on vacation closer to the mountains. The air, characteristic of those places, helps to increase hemoglobin well. Turn without drugs and special diet products. You should always eat in a balanced way during the rest, too.

With low acidity, iron in the body is absorbed worse.

Treatment for low hemoglobin

For effective treatment, the cause must be eliminated. It can be: removal of fibroids, hemorrhoids, treatment of ulcers, enteritis, etc.

The introduction of an iron preparation. The dose should not exceed, usually 100-300 mg. per day. When normal hemoglobin is reached, do not stop treatment, but continue for another 2-3 months.

If it is revealed that low hemoglobin is directly related to insufficient intake of vitamin B12 in the body. In this case, it is mandatory to prescribe subcutaneous injections (cyanocobalamin), it is administered at 200 – 500 mcg once a day, for 4 – 6 weeks. Normalization occurs after 2 months, but vitamin B-12 continues to be administered for another 2-3 months. Once a day.

When taking iron supplements, don’t expect too fast results. After therapy has begun, after 10 days, iron increases several times. This means that treatment with this drug is effective for this organism.

Iron accumulates first in the liver, only then enters the bloodstream, so taking the drug can last up to six months, but not less than one month.

If it is a helminthic invasion, then it is recommended to carry out deworming. For diarrhea, for example, it is good to use enzymes, and of course a special diet that includes more vitamin C, as it helps the iron to be absorbed faster.

During treatment, it is recommended to abandon dairy products, they, or rather the calcium contained in them, on the contrary, interfere with absorption. You cannot refuse cheeses, cottage cheese, milk, then take an iron preparation before eating food 5 hours before, or after eating 5 hours later.

Also contributes to the absorption of iron in the body dark varieties of honey. But tea and coffee interfere with the absorption of iron, do not abuse it.

Iron deficiency in the body along with vitamin B – 12, there is also a lack of folic acid. Then folic acid is also added to the ongoing treatment, 5-15 mg per day, the course of days is 20-30.

According to the degree of decrease in hemoglobin (iron deficiency anemia), they are divided into:

  • The degree is mild, 110-90 ch.
  • The degree is average, hemoglobin 90-70 hl.
  • The degree of severe – below 70gl.

If you do not increase hemoglobin, the truth may not immediately occur, changes in the body, with irreversible consequences. Reduced hemoglobin will lead to anemia, which can be deadly. Be sure to see a doctor, with the symptoms described above, proceed immediately to the diet.

The danger is that the symptoms of this disease are not immediately recognizable, and, accordingly, measures are not taken in time.

Your child does not eat well, quickly overworks, if there is also a growth retardation, sound the alarm, urgently take tests. Believe me, this is not a trifle, and deserves close attention.
Do not put off going to the doctor, at the slightest symptom, take tests.

Eat right, walk more in the fresh air. I wish you all good health!
