Losing 30 pounds may improve insulin resistance to a certain extent, but not necessarily complete recovery, should be judged according to the causative factors. If it is caused by obesity, it may recover gradually; if it is accompanied by diabetes, polycystic ovary syndrome and other underlying diseases, it may be difficult to recover and should be treated with medication. Insulin resistance can be caused by obesity, if through diet control, active exercise and other life interventions to reduce weight to normal range, insulin sensitivity may gradually recover. However, if you do not pay attention to weight control after recovery and gain weight again, insulin resistance may reappear. Some insulin resistance may be difficult to recover even if weight loss is successful, which is mainly related to endocrine diseases such as diabetes, polycystic ovary syndrome, etc. It is recommended to go to the hospital in time for regular treatment, and follow the doctor’s instructions to take medications such as metformin to improve insulin resistance. If there is any discomfort, consult a doctor promptly.
