The management of a diabetic patient who is getting thinner depends on the cause. If it is caused by diabetes itself, it can be remedied by adjusting the glucose-lowering regimen, paying attention to diet, and adjusting medications. If it is caused by other diseases such as tumor, it needs to be treated for the original disease. 1. Adjustment of glucose-lowering program: firstly, check how the blood sugar control is, go to the endocrinology department in time, and adjust the glucose-lowering program under the doctor’s guidance. When the blood sugar of diabetic patients is not well controlled, the peripheral tissues have impaired utilization of glucose, increased lipolysis, and protein metabolism is negatively balanced, resulting in the symptoms of wasting. 2. Pay attention to diet: If patients overdo diet control, the calories consumed by daily exercise greatly exceed the calories ingested every day, which will lead to getting thinner and thinner, therefore, excessive starvation is not advocated in diet, so as not to lead to nutritional imbalance. 3. Adjustment of drugs: some of the glucose-lowering drugs in the process of taking will lead to the adverse reaction of thinning, common metformin, dagliflozin and so on. These drugs also have the effect of weight loss in the process of lowering sugar, which will also lead to patients getting thinner and thinner, so if the adverse reaction of wasting occurs, you need to adjust the drugs under the guidance of the doctor in a timely manner. In addition, there are other diseases such as tumors, tuberculosis, etc. can also cause patients to continue to lose weight, and need to be treated for the original disease. It is recommended that when diabetic patients continue to lose weight, they should go to the hospital in time to get a clear diagnosis and targeted treatment.
