Risks and Side Effects of Gastric Sleeve Surgery

Gastric Sleeve surgery can help you maintain the weight loss goals you previously thought impossible. It is important, though, to know the side effects and potential risks of gastric sleeve surgery before opting for the procedure:

Nausea and vomiting are common occurrences, mainly within the first three months after the gastric sleeve procedure. As you become more accustomed to your new dietary restrictions, including smaller portions and healthier eating habits, overeating and improper chewing may occur. This can result in a number of side effects, including nausea and vomiting.

Extreme weight loss can also lead to serious dehydration, and a failure to consistently replenish your body's fluids can result in further side effects, including vitamin deficiencies and electrolyte imbalance. Symptoms of dehydration include light-headedness, dizziness, fatigue, and lower back pain. You should be sure to drink six to eight cups of water daily in order to prevent dehydration, while also avoiding liquids during meals.

Hair thinning can also occur within the first year after gastric sleeve surgery due to a nutritional deficiency. Your Gastric Sleeve Center medical team will monitor your progress and recommend specific supplements to help combat any potential deficiencies. In the majority of cases, hair thinning or loss is purely temporary and will grow back.

Intolerance to certain foods can occur following your gastric sleeve surgery. In many cases, foods that are very dry, sticky, or stringy, including peanut butter, roast beef, and fibrous fruits and vegetables can lead to pain, vomiting, or nausea. It may become necessary to limit or completely avoid these. Alcohol should be avoided as there is a chance its effects could be increased for gastric sleeve patients. Your Gastric Sleeve Center nutritionist will be sure to review the various foods and beverages you will want to limit or avoid after you undergo gastric sleeve surgery.


Maintaining strong communication with the Gastric Sleeve Center will help you avoid many of the post-surgery complications and side effects from Gastric Sleeve surgery.
