Taking insulin for diabetes generally does not affect the couple’s life. The main role of insulin for diabetic patients is to lower blood sugar and control blood sugar level, which generally does not affect sexual function and has no effect on couple life. If a diabetic patient’s condition is more serious or the history of the disease is longer, causing sexual dysfunction, it may indirectly affect the couple’s life. If a diabetic patient needs to take insulin to control blood sugar, he or she must strictly follow the doctor’s instructions to use the correct amount of injection, not too much or too little, so as not to bring health hazards to himself or herself. It is recommended that diabetic patients use insulin treatment, regular review to the hospital endocrinology or diabetes specialists, pay attention to the detection of blood glucose value, with the doctor to reasonably adjust the use of insulin dose. If there is any discomfort, consult the doctor in time.
