Hypertension usually does not lead to weight loss, but if hypertensive patients experience significant weight loss and substantial weight loss within a short period of time, they should consider the combination of other diseases, the most common being hyperthyroidism, which may be characterized by high metabolism, such as significant weight loss, increased appetite, abnormal bowel movements, accompanied by panic and hand tremors. In this case, it is necessary to go to the endocrine clinic as soon as possible to improve thyroid function tests to clarify the diagnosis. In addition, you should also pay attention to whether you have chronic wasting diseases, such as ulcerative colitis, poor feeding, poor digestive function, etc. You need to go to the gastroenterology department to improve the examination for clarification. It is also important to note that malignant tumors and other diseases can cause weight loss in a short period of time, so weight loss needs to be diagnosed as soon as possible and treated in a timely manner.
