Many people dream of losing weight as safely and quickly as possible. Gastric bypass surgery is an effective and quick way to lose weight even when diet and exercise have failed. But what should you do after the surgery? What should you be prepared for? For example, side effects such as extra bloating or gas may occur during the recovery period. How can you relieve pain after gastric sleeve? Let’s figure it out.

Causes of Gas After Bariatric Surgery

After bariatric surgery, the digestive system undergoes changes. These can affect the normal process of digestion and absorption of food. The reduction in the size of the stomach, sometimes together with changes in the small intestine, can lead to the fact that food is not fully digested before it reaches the large intestine. In this area, intestinal bacteria ferment it, producing gas. Insufficient secretion of pancreatic enzymes after surgery can lead to poor digestion of fats and proteins.

The intestinal microbiota can be altered after surgery due to changes in the stomach’s pH level and some areas of the intestine, which contributes to excessive gas formation. Painful or foul-smelling gas after gastric bypass can be pretty uncomfortable. But we hasten to reassure you.

Some gas after such an operation is standard. You need to get through this period, and soon, you will feel better. Do you have stomach pain due to gas years after gastric bypass? That’s when it’s a problem, and you should see a doctor. Let’s look at the causes of gas after bariatric surgery.

The fact is that the gastrointestinal tract may stop effectively absorbing or breaking down nutrients after this operation. In addition, you generally change your diet, which can also initially cause discomfort and lead to additional gas formation.

Common Symptoms Associated with Passing Gas After Surgery

Patients undergoing this weight loss surgery often experience bloating. This is usually the result of gas buildup in the digestive system because the stomach is smaller and more sensitive. Gas can cause abdominal pain, especially in the first few weeks after surgery. Just give your body time to adjust to the changes. Burping and flatulence often increase after surgery. This is a natural release of excess air and accumulated gas.

How Long Does Gas Pain Last?

Gas after surgery usually doesn’t last very long, and that’s good news! You’ll usually feel relief within 1-2 days. Walking will greatly help relieve gas, so stay active (if your doctor allows it, of course). Unfortunately, gas can return at any time. The culprit is usually the food you eat. Learn what foods your body can digest and follow a proper diet.

Of course, you need to see a doctor first. But this article is about what else you can do to alleviate your condition. So, a patient may experience gas after gastric bypass, accompanied by constant pain. How to cope?

Be Mindful Of What You Eat 

You had bariatric surgery to lose weight. After surgery, you should follow a diet. This is especially important if you suffer from gas. The more food you eat, the more your body has to break down. Constantly undigested food causes gas. Also, try to eat more slowly. The faster you eat, the more likely you are to have gas.

Chew Your Food Thoroughly 

Mindful eating is incredibly beneficial, especially after bariatric surgery. Chew your food 20-30 times per bite. This will help speed up your digestion and reduce excess gas.

Beware of Foods That Can Cause Flatulence 

Dairy products, beans, and alcohol can cause excessive gas. At this time, avoid cabbage, cauliflower, broccoli, Brussels sprouts, asparagus, turnips, arugula, radishes, leeks, onions, garlic, asparagus, artichokes, potatoes, and carrots. Also, you should avoid legumes such as beans, peas, and lentils for a while.

Use Probiotics

Probiotics are beneficial microorganisms. They help you digest food faster. Take probiotic supplements so your body can break down food more efficiently. This means less fuel for gas.

Avoid Chewing Gum and Smoking 

The point is that chewing gum and smoking contribute to introducing air into the gastrointestinal tract, which provokes gases.

Limit the Consumption of Carbonated Drinks

Such drinks contain gas, which then puts pressure on the intestines and stomach.

Eat Small Portions Throughout The Day, Not Three Large Meals

If you want to reduce gas and bloating, eat small portions throughout the day, not three large meals.

Avoid Fatty and Spicy Foods

Such foods can lead to the accumulation of intestinal gases in the stomach, causing discomfort.

Heating Pads/Hot Bath 

This is a good way to relieve some discomfort. This method has helped many patients. But always listen to your condition. An individual approach is important.

Take Medications

See your doctor about medications that can help you feel better. There are also over-the-counter medications that your surgeon may recommend. Look into lactase supplements and alpha-galactosidase supplements. These supplements can help reduce bloating after gastric bypass surgery.

Stay Active

Live an active lifestyle. The more water you drink and the more active you are, the better your body will convert food into energy. Gases will not stagnate in the intestines. Even a short 20- or 30-minute walk can help.
