Into the middle age, many women will face the same problem, eat not much, but the weight is hard to grow, and often there will be sluggishness, to the hospital to check and can not find the problem, and even doubt that they are in advance of dementia. In fact, when this happens, you can check the thyroid gland to see if you are hypothyroid. Hypothyroidism is an autoimmune disease that produces its own antibodies against thyroid tissue, and this antibody slowly destroys the thyroid tissue. Initially, after a little bit of thyroid tissue damage, it will not affect the organism, but if the autoimmune process doesn’t stop, the chronic inflammation slowly develops, and eventually, as you get older and older and longer and longer, you will always show the problem of not enough thyroid hormones. This is why middle-aged and elderly people are more likely to suffer from “hypothyroidism”. Weight gain is a sign of hypothyroidism, and hypothyroidism is often confused with Alzheimer’s disease, in which symptoms such as decreased metabolic rate, loss of energy, low work efficiency, poor memory, and reduced learning ability can be mistaken for dementia, and even delayed. It may even delay the condition. In addition to the symptoms similar to Alzheimer’s mentioned above, rapid weight gain in women in their middle and old age may also be one of the manifestations. Some women eat less, but always gain weight because the metabolic rate of the body decreases due to the decrease in thyroid hormones, and they are not able to consume the calories they take in well, so they tend to gain weight. Deliberate iodine supplementation is not a good way to prevent hypothyroidism, many people will go into the iodine supplementation the more the better the misunderstanding, and this will be counterproductive. Now there is iodine in the salt, and the Liaoning area is not iodine-deficient, coupled with the northeastern people “heavy mouth” diet, the existing iodine salt iodine content has been sufficient to meet the needs of the human body, intentionally added to the table with the seaweed, eating seaweed in the snacks rather unfavorable. Sometimes, excessive iodine intake can induce thyroiditis. Therefore, for middle-aged and elderly women, when there is inexplicable rapid weight gain, mental depression, you can go to the hospital for laboratory tests, not in order to avoid “hypothyroidism” and deliberately supplement iodine.
