What should I do if I am too light and too thin? ? According to the calculation standard of body mass index (BMI) published by national health institutions, the normal BMI of adults should be maintained between 18.5(kg/m2) and 24(kg/m2). If it is lower than 18.5, it is overweight and underweight. If it is lower than 16, it will be severely reduced.
Six diseases and symptoms that may occur if you are too thin. If you are underweight or even severely underweight, you are likely to lose six diseases or symptoms:
First, osteoporosis:
Orthopedics doctors point out that gravity can make bones denser, and maintaining ideal weight is the best way to maintain gravity. According to statistics, the probability of osteoporosis in people with a body mass index greater than 18 is much lower than that in people with a body mass index less than 18, especially in thin women. Because of the lack of estrogen in the body, it will affect the combination of bone and calcium and cannot maintain normal bone density. Many young women under the age of 30 have lower bone density than women aged 4 or 50.
Second, the immune function declines:
Too thin people often have unbalanced nutrition and insufficient vitamin intake, which easily leads to the decline of immunoglobulin and immunity, weak resistance to pathogenic microorganisms such as viruses and bacteria, and prone to symptoms such as colds, fever and fatigue. Some people who are too thin can even affect the gastrointestinal function, leading to indigestion or ulcers.
Because the energy stored in the body is insufficient, people who are too thin can't cope with external influences. Once they get sick, the recovery time of the disease will be prolonged.
Third, anemia:
Too thin people generally have the problem of unbalanced nutrient intake, and iron, folic acid, vitamin b 12 and other hematopoietic substances are insufficient. Because of eating less, the basal metabolic rate is lower than that of ordinary people, so the gastrointestinal movement is slow and the gastric acid secretion is less, which affects the absorption of nutrients. These are the main causes of anemia. As mentioned earlier, malnutrition can also lead to the decline of the body's immunity and easily lead to secondary anemia.
Four, impaired renal function, hematuria:
Too thin human body has insufficient fat content, which leads to loose connective tissue around the kidney and weak muscles, which can not provide external muscle protection that the kidney can rely on, leading to kidney drooping, internal venous blood oozing, hematuria and backache.
Five, gastroptosis:
The cause of this symptom is very similar to the renal function damage mentioned above. When the human body is excessively emaciated, the abdominal wall in the body is slack and the abdominal muscles are weak, which leads to the weakness of the muscles and ligaments that suspend and fix the position of the stomach, and the abdominal pressure drops, so the physiological position of the whole stomach is reduced and the gastric peristalsis is weakened, which leads to gastroptosis.
People with long-term gastroptosis will have dizziness, headache, insomnia, palpitation, fatigue and other symptoms due to psychological and mental factors or anemia, emaciation and other factors, and a few even have depressive symptoms.
Six, skin relaxation and skin diseases:
People who lose weight too fast and lose weight will cause skin relaxation because of excessive subcutaneous fat loss, and the skin supported by fat has long lost its elasticity, so when there is no subcutaneous fat and muscle support, the relaxed skin will become wrinkled and uneven.
If the elderly are too thin, due to the decrease of sebaceous gland secretion, the skin will become thin and dry, which is easy to cause senile skin diseases such as keratinization and chronic skin itching.
