Attract amenorrhea: In recent years, there are often dieters in gynecological clinics who see a doctor because of irregular menstruation or even amenorrhea, mostly young women around the age of 20. They restrict their diet and lose weight sharply, which is called weight loss amenorrhea. This kind of amenorrhea is mostly secondary amenorrhea, and the patient has no organic disease or mental illness, which is completely caused by rapid weight loss caused by dieting. Because adolescent women need to accumulate a certain amount of fat (about 17% of the total weight) to make menarche come as scheduled and keep the regularity once a month. If you lose weight blindly and lose body fat, you can delay menarche, and those who have already come to menarche can have menstrual disorder or amenorrhea.

Inducing gallstones: Dieters' low-calorie and low-fat diet can cause gallstones in patients. The reason is that the gallbladder can't deliver enough bile to the small intestine when the hunger is caused by the sudden decrease of fat and cholesterol intake. The coexistence of cholestasis and supersaturation of bile salts will promote the formation of stones. One of the ways to prevent the formation of stones is to make the gallbladder fully contract and empty at least once a day. Dieters should consume at least 65,438+0,200 kilocalories every day, and a meal every day must contain 5-65,438+00g of fat to stimulate the gallbladder to empty completely, thus preventing the formation of gallstones.

Damage to brain cells: A new research topic shows that dieting and losing weight is very harmful to brain memory function cells, which will cause these dieters to forget more and more, and even simple calculations will not be able to cope in the future. Physiologists believe that the result of dieting is the lack of nutrition in the body, which makes the damage of brain cells more serious and directly affects memory and intelligence. The researchers studied the effects of dieting on the brain health of 55 women. The women who participated in the experiment were regularly evaluated in terms of weight, body shape and behavioral response.

The results showed that all 55 dieting women had memory loss and slow response. Further research found that the longer the dieting time, the worse the weight loss effect, and the worse the performance in digital recognition, behavior and intelligence.

Osteoporosis: The American Institute on Aging recently conducted a survey on 3683 women over 67, and plotted their weight changes at the age of 50 and the incidence of hip fractures in the next eight years. The results show that if the healthy women lose more than 10% at the age of 50, the probability of hip fracture at the age of 65 is nearly twice as high as that of women with stable weight. The incidence of hip fractures in thin women is much higher. Why are women who are thin or lose too much weight prone to hip fractures? "Menopause", especially for postmenopausal women, due to the cessation of ovarian function, the production of estrogen is greatly reduced, resulting in a large loss of bone calcium, which is easy to cause osteoporosis and fractures. Adipose tissue is an important place to produce estrogen in the body except ovaries. Adipocytes can be processed to convert raw materials provided by adrenal cortex into estrogen. Therefore, women who are thin or lose too much weight often have low estrogen levels, which is easy to cause osteoporosis and fractures.

Hair loss: According to the statistics of clinical data, the number of hair loss caused by weight loss is increasing, among which young women aged 20-30 account for 20-30%. Because the main component of hair is protein, trace elements such as zinc, iron and copper are also sand; People who are vegetarian and lose weight only eat vegetables, fruits and flour, and their intake of protein and trace elements is insufficient, which leads to serious malnutrition and hair loss.

It is reported that a 13-year-old girl imitated her mother to lose weight, and as a result, she suffered from anorexia nervosa, which almost threatened her life.

This is one of the most common manifestations after losing weight. According to the research, the normal menarche can only be guaranteed if the fat content of adolescent girls accounts for more than 17% of their body weight, while the fat content of adult women is less than 20%, which will affect the menstrual cycle, and in severe cases, dysmenorrhea, amenorrhea and even uterine bleeding will occur.

■ Hazard six depression

After implementing the weight-loss plan for a period of time, some women find that their work efficiency drops, they are prone to lose their temper and often feel depressed, accompanied by symptoms such as dizziness, headache, insomnia and loss of self-confidence.

Anorexia nervosa is stubborn and needs to see a doctor as soon as possible.

■ Injuring the eight organs is more likely to be damaged.

Neutral fat is the body's reserve fat, which is mainly distributed under the skin, abdominal cavity and around organs, and plays an important role in protecting and fixing various organs and maintaining body temperature. If you lose too much weight, it will cause sagging of important organs such as stomach, uterus and kidney. When you are injured by external force, without the buffer and protection of fat, the injury of internal organs and the occurrence of fractures will increase obviously.

Diarrhea is harmful to weight loss.

People usually defecate once a day. If they defecate many times a day and have loose bowels to lose weight, they think they have lost weight, and even think that loose bowels are necessary to lose weight. This is really a big mistake.
