Are you planning on having gastric bypass surgery? Have you considered what you shouldn’t eat?  When you get gastric bypass surgery, your stomach is made smaller so you only have a pouch that your food goes into. Additionally, your intestines are rerouted. This means that your digestive system will work a little differently. Because of this, there are foods to avoid after gastric bypass surgery.

Foods You Can’t Eat After Gastric Bypass

There are a few foods that you will want to avoid after your gastric bypass surgery. These include high-fat and high-sugar foods, as well as anything that is difficult to digest. It is important to take things slowly in the beginning and ease your way back into eating solid food. Start with simple, soft foods and work your way up to more complex dishes.

We all have dreams of what we will eat after surgery, but there are some things you cannot eat. No matter how much you want to eat something, certain foods should be avoided after your surgery. Here are some of those foods to avoid after weight loss surgery..

You should also avoid drinking carbonated drinks. These sugary drinks will cause gas and bloating, which is the last thing you need after surgery. Stick to water or other unsweetened drinks instead.

High Seasoned Foods

You should avoid high seasoned foods after surgery. These can be hard to digest and cause discomfort. Stick to low or no seasoning foods.

Nuts and Seeds

You should avoid eating nuts and seeds after surgery. These foods are hard to digest and can cause discomfort. Stick to other types of food instead.

 Alcoholic Beverages

After surgery, you should avoid consuming alcoholic beverages. These can be difficult to digest and cause discomfort. Instead of alcoholic beverages, drink water or unsweetened alternatives.

Caffeinated Beverages
