Suddenly lost a lot of weight. It must be a physical problem. At this time, you must go to the hospital for examination, because there are many reasons for sudden weight loss, such as endocrine, tumor or some chronic diseases, which will all cause weight loss, so don't ignore it. No matter how tired you feel recently, when you are tired, it will really cause weight loss, but it is generally only a few pounds, because it only consumes water in your body. First of all, we should consider whether it is a digestive tract problem, especially a pathological change in the intestine, because the food we eat is slowly decomposed through the digestive system and transported to our intestines for absorption. Any mistake in the middle link will lead to some obstacles in our digestion, hinder our absorption and lead to weight loss. We should also be alert to the influence of malignant tumors. We have cancer, the most obvious thing is that we will lose weight in the early stage, because tumors need a lot of nutrients to grow in our bodies, and they will constantly absorb nutrients from our bodies, leading to our weight loss. Therefore, the annual physical examination is very important. If you find a tumor, don't give up. If many malignant tumors are treated in time in the early stage, the impact on our lives will not be too great. Weight loss may also be a manifestation of diabetes or other endocrine problems. For example, if there is a problem with the thyroid gland, it will affect all aspects of the body and cause weight loss; It is very normal for diabetics to lose weight. If it is an endocrine problem, as long as it is well conditioned, it will soon return to normal. They must keep their body and mind happy, and their moods and emotions have a great influence on their bodies.
