cholelith
Bile is secreted by the liver and contains cholesterol, bile salts, calcium and lecithin. And they keep a certain proportion. Too thin people have insufficient calorie intake, so the body fat will be consumed at an accelerated rate, and cholesterol will also change accordingly, leading to an increase in bile secretion by the liver, and bile liquid is viscous and has crystal precipitation, that is, gallstones.
gastroptosis
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.
anaemia
People who are too thin generally have the problem of unbalanced nutrition intake, such as insufficient intake of hematopoietic substances such as iron, folic acid and vitamin B 12, coupled with lower basal metabolic rate than others, slow gastrointestinal peristalsis and less gastric acid secretion, which affects the absorption and utilization of food nutrition, so anemia.
Osteoporosis
The incidence of hip fracture in thin women is higher than that in standard weight women 1 times. It is because the level of estrogen in the body is insufficient, which affects the combination of calcium and bone and cannot maintain normal bone density, so osteoporosis will occur and fractures will easily occur.
metroptosis
If the uterus does not have enough fat, it may descend along the vagina. For underweight people, in severe cases, the cervix droops and falls off from the vaginal opening, leading to uterine prolapse. In some specific cases, it can also cause cervical infection and cervicitis.
haematuria
The kidney is surrounded by a layer of connective tissue. If people are too thin and low in fat, resulting in loose connective tissue and muscle weakness, they can no longer protect the kidneys. The kidney is prone to drooping, leading to venous blood oozing, hematuria, and backache.
lose hair
Hair contains trace elements such as iron, copper, zinc and protein. Too thin people have insufficient supply of body fat and protein, so their hair frequently falls off and their hair color gradually loses its luster.
Memory decline
Many people don't know that the main driving force of human brain work comes from fat, which can stimulate the brain, accelerate the brain's ability to process information, and enhance short-term and long-term memory. People are too thin, eat less fat and store less. Malnutrition causes brain cell damage, which will directly affect memory.
duodenal stasis
The cross section of the duodenum is located behind the peritoneum and is the most fixed part of the digestive tract. Too thin people, the mesentery and retroperitoneal fat are scarce, and the internal organs droop, which virtually narrows the gap between the spine and the proximal end of the superior mesenteric artery, resulting in duodenal compression.
Can women who are too thin lead to infertility?
Women's body fat percentage must reach at least 17% to maintain normal menstrual cycle and sexual desire level, which is also the minimum fat standard for their healthy pregnancy, delivery and breastfeeding in the future.
Because adipose tissue can convert the raw materials provided by adrenal cortex into estrogen, it is an important place to produce estrogen in the body except ovaries.
If there is too little fat in the body, it will affect the synthesis of estrogen and its concentration level in the blood, resulting in insufficient estrogen level, which is one of the key criteria affecting women's fertility.
How should women supplement nutrition in different periods?
1. Adolescent women: The absorption of calcium and iron is the key.
The demand for calcium in adolescence is greater than that in other age groups, because bone growth and bone density are mainly formed at this stage.
Iron is also necessary for the growth and development of adolescent girls. At this stage, the blood volume and muscles in the body are greatly increased. Iron is an essential substance for the synthesis of heme and myoglobin in the body, which needs adequate supply. In addition, girls lose iron every month because of menstruation, so women need to pay more attention to iron supplementation.
2.20-year-old women: pay attention to the intake of vitamin C.
For women around the age of 20, this stage is usually the most energetic and physically exhausted period. In addition to a balanced diet, we should pay special attention to the intake of vitamin C. Environmental and emotional stress will increase the demand for vitamin C.
3.25~40-year-old women: pay attention to supplement collagen and antioxidant food.
Collagen is an essential nutrient for women to delay aging. Women enter the peak of collagen loss at the age of 25, and the content of collagen at the age of 40 is less than half of that at the age of 18.
The wrinkles on the face of the elderly are precisely because of the loss of collagen and water, which leads to skin collapse. Keeping collagen supplement can promote the supporting ability of elastic fibers in dermis to skin.
Women aged 4.45-55: Calcium intake is still the key point.
Women aged 45-55 are facing the discomfort of menopause and the threat of osteoporosis, and calcium intake is still the focus. At this stage, women need to consume about 1000 mg of calcium every day. Menopausal women should also eat more soy products. Bean products such as tofu and soybean milk are rich in soybean isoflavones.
Women after the age of 5.60: Pay more attention to calcium supplementation.
After the age of 60, due to the decrease of activity and metabolic rate, the calories needed by the elderly are reduced. Try to choose oil with high unsaturated fatty acid content, reduce the intake of saturated fatty acid and reduce the content of cholesterol in blood. When you get old, you should pay more attention to calcium supplementation, such as a bag of milk or soybean milk every day.
