Weight loss surgery can help people manage their weight and associated health concerns, including high blood pressure, diabetes, and sleep apnea. While weight loss surgery is considered as safe as most other surgeries, there are common and very manageable complications of weight loss surgery that patients should know before choosing this option. 

What are some risks associated with weight loss surgery?

Aside from the risks that are common with all surgeries, including pain, anesthesia reactions, bleeding, and infection, weight loss surgery has a few specific side effects that patients may face. These side effects include nutritional deficiencies, "dumping" syndrome, gastrointestinal issues, mental and emotional challenges, and the possibility of regaining weight. 

Nutritional deficiencies and weight loss surgery

Experiencing nutritional deficiencies after weight loss surgery is a common complication. Patients may experience a reduced absorption of essential vitamins and minerals, which can lead to anemia, osteoporosis, and neurological issues. Post-operatively, patients are given a strict diet to adhere to.  They are also prescribed supplements to help combat any nutritional deficiencies they may experience. Nutrient levels are also monitored through routine blood tests, allowing us to catch any deficiencies before they become big problems. 

What is dumping syndrome after weight loss surgery?

Bariatric surgery reduces the amount of food a stomach can intake and in some cases, may alter the digestive track. Because of these changes, food may move (or "dump") from the stomach into the small intestine too quickly. This can lead to feelings of nausea or dizziness and diarrhea. Eating smaller, more frequent meals, avoiding high-sugar foods, and remaining hydrated can help patients avoid dumping syndrome. 

Gastrointestinal issues after weight loss surgery

Some gastrointestinal issues can arise after weight loss surgery, including bowel obstructions or ulcers, which may require medical attention. Any persistent abdominal pain or changes in bowel habits should be reported to a patient's health care provider as soon as possible. 

Mental and emotional effects of weight loss surgery

Not only does weight loss surgery lead to a change in physical health, but it can also have an impact on the mental and emotional health of patients. Support from mental health professionals, support groups, and loved ones is vital in managing the psychological aspects of weight loss. 

Weight plateaus and regain

Bariatric surgery helps individuals lose weight and regain physical health, but is not a cure-all. Weight plateaus and regain may occur due to lifestyle changes, hormonal changes, or not following post-operative guidelines. Working with a registered dietitian and healthcare providers can help patients stay on track with their post-surgery plan.
