Nausea and Vomiting

A lot of bariatric surgery patients can experience nausea and vomiting at some point as they adjust to new eating habits, such as when to eat and drink and how much to consume and how fast. However, contact your bariatric surgery team if you're vomiting or can't determine the cause of your nausea or vomiting.

Gastrointestinal Issues

Some patients experience constipation and gas/bloating after bariatric surgery, whereas others may have diarrhea Bowel movements eventually settle down and may be changed from before the operation. Unless troublesome, there is no need to worry. Try to incorporate fiber and adequate liquids in your food as it is the simplest way to regularize your bowel movements. Contact your physician if you need help and are troubled by your bowel movements.

Dumping Syndrome

If you eat and drink simultaneously, or if you eat high carbohydrate foods or sweets, you may experience severe diarrhea, nausea, light-headedness, and stomach cramps. This is called dumping syndrome and it is usually self-limiting. This is why bariatric surgery patients are strongly encouraged not to drink anything with meals, limit sugar intake, and eat low carbohydrate foods.

Weight Gain

While bariatric surgery is highly effective for weight loss, it's only a tool. You must adhere to recommended diet restrictions, eating habits, and lifestyle changes to maintain results. If you're struggling with weight gain after surgery, contact your bariatric surgery team or join a support group.


Low blood sugar can occur after bariatric surgery but usually happens long after having the procedure. If you feel dizzy, clammy, sweaty, and like you may pass out, contact your bariatric surgery team. If hypoglycemia is left untreated, it can lead to seizures.

Commonly occurring about four weeks after surgery, symptoms include difficulty in eating or vomiting after eating or drinking that gets worse over time, the sensation that food is stuck in your esophagus, not being able to tolerate certain foods, being unable to accept solid foods after the initial liquid diet, and experiencing pain when eating solid foods. Contact your bariatric surgery team immediately if you have any of these symptoms. While this can be treated with an outpatient procedure, it must be treated as soon as possible.

Hair Loss

Vitamin Deficiencies

Vitamin deficiencies are common when patients don't take vitamins or choose to take a generic over-the-counter multivitamin. To prevent vitamin deficiencies, bariatric multivitamins are available. It is advisable to regularly take the supplements prescribed by your bariatric surgeon.


Sores in the lining of the stomach or small intestine are possible anytime after bariatric surgery and cause severe, persistent nausea and pain, especially with eating. Early detection is vital, so contact your physician if you're experiencing any symptoms. Ulcers can be treated with anti-ulcer medications.

  • Severe pelvic pain
  • Fever (over 101째)
  • Inability to urinate or empty your bowels
  • Anxiety, sweating, chills
  • Nausea and vomiting
  • Persistent hiccups (with other symptoms)
  • Color change in drainage from incisions

When to Seek Immediate Medical Assistance

You should call your bariatric surgeon or seek emergency care if you experience any of the following:

  • Chest pain that's getting worse
  • Difficulty breathing when at rest
  • Fever over 101째
  • Pain, redness, or swelling in the legs (indicative of blood clots)
  • Increased drainage, swelling, or pain at incision sites
  • Incision drainage that is green or pus-like or has a foul smell (normal drainage is yellowish-red in color and odorless)
