Before beginning any surgical operation, the patient often gives the bariatric surgeon a complete and detailed medical history. Prior to surgery, a morbidly obese person’s linked health conditions like diabetes, hypertension, sleep apnea, hormonal imbalances, infertility, etc. should be optimised. After speaking with the appropriate specialised doctors and reviewing the present medicine, this is done. In addition to the patient’s medical issues, the doctor must comprehend the patient’s nutrition and lifestyle in order to guide the patient in selecting the best course of action. The surgical treatment that is most appropriate for a given patient will be determined by a variety of additional characteristics, such as age, gender, motivation, level of physical activity, capacity to adhere to dietary supplements, and long-term follow-up.
