Bariatric surgery is a relatively special way of weight loss, which requires only one surgery to allow patients to lose a large amount of excess weight within a year, but also can simultaneously treat a variety of obesity complications, has become the preferred way of weight loss for many morbidly obese patients. However, there are some patients who report that they often experience constipation after weight loss surgery, so what’s going on? Constipation is a relatively complex symptom, there are many triggering factors, such as work stress, fast pace of life, too little activity may cause constipation, and these factors have little to do with the weight loss surgery, weight loss surgery caused by dietary problems may cause constipation. After the surgery, the patient’s stomach capacity will become smaller, the diet is restricted, coupled with the body in order to replenish nutrients, may reduce the intake of food rich in dietary fiber and reduce the amount of drinking water, coupled with the recovery period of less exercise, so resulting in constipation. To deal with this situation, the patient should consume some boiled vegetable leaves to increase the intake of dietary fiber around the fourth week after the operation, and at the same time maintain proper exercise and sufficient water intake (generally above 2000ml) every day, and then tell his/her health manager about his/her recovery and diet, etc. (Generally, medical institutions that do weight loss surgery will have special health managers to follow up on the patients), so that they can make recovery decisions based on their factual situation. They will make adjustments to the recovery program and dietary guidance according to their own facts. If you have persistent constipation, it is recommended that you go to the hospital to see a doctor who specializes in constipation or endocrinology, so that you can get a more professional solution.
