Well, one of the most frequently asked questions by patients to obesity surgeons is what type of diet and lifestyle they need to follow after Bariatric surgery. Most bariatric surgeons offer their patients tailored nutrition plans based on the type of surgery performed and the patient’s unique health and lifestyle factors. Maintaining adequate bariatric nutrition and lifestyle after surgery is crucial for an optimal outcome.

A surgeon or nutritionist will talk to you about the nutrition you need to follow after surgery and explain what type of food and how much you can eat with each meal. If you are following the diet, you can lose weight safely.

Bariatric surgery is an essential step in the right direction for significant weight loss. However, surgery alone is not enough to succeed in the long run. Adherence to an adequate bariatric diet plan and lifestyle after surgery is crucial for optimal patient outcomes.

Dr. Venu Gopal Pareek provides the details of a diet and lifestyle after the surgery in this blog. This will give you a good idea of what to expect after bariatric surgery.

Below are the diet and lifestyle changes after bariatric surgery

Depending on the procedure you are considering and your life before surgery, you might expect different changes. The surgeon will talk to you about these possible changes during your surgery and consultation. Here are some lifestyle changes that most patients can expect:


When you leave the hospital after surgery, you will receive a prescription for some medicine. Some of these drugs are taken some days after surgery, while others for a lifetime. One of them is an acid-reducing drug called “proton pump inhibitor” (PPI). Omeprazole prevents ulcers. If you have a gallbladder, you will be given a prescription medication to prevent gallstones.

All these pills must take in crushed form, and capsules opened. You will not be able to take complete pills as before surgery, and you may have difficulty moving through your new digestive system. After surgery, you should continue to take regular medication for other conditions. Consult a surgeon regularly to make sure you are taking the right dose. You can choose lower dosages for obesity if required and prescribed by the surgeon.

Do not take nonsteroidal anti-inflammatory drugs (NSAIDs) such as Aspirin, Ibuprofen, Diclofenac, Naprosyn, Rofecoxib, and Celecoxib. These medicines increase the risk of developing ulcers. Ulcers are more challenging to diagnose and treat after the surgery. Ask a doctor if you are starting a new treatment.

Vitamins And Supplements:

You must take the following vitamins and supplements every day to help prevent nutritional deficiencies.


Take a beneficial multivitamin and mineral that contains iron and folic acid. Daily selenium, copper, and zinc. Take As per doctor’s prescription.


Take calcium daily to prevent bone deficiencies. To increase absorption, use calcium supplements. Take As per doctor’s prescription.

Vitamin D:

Take Vitamin D every day. If you want, you can take a combination of calcium and vitamin D, provided that it contains the right dose to prevent having some pills.

Vitamin B12:

Take B vitamins every day. It should take as a tablet or liquid under the tongue. Remember to crush any pill that you take. You may need extra folic acid or iron, especially if you are a woman and are still having menstruation. A nutritionist provided by the surgeon will discuss this with you.

Birth Control and Pregnancy:

We recommend that women who have the potential to give birth to use effective contraception for the first year after bariatric surgery. The physical demands of pregnancy on your body can affect the fetus and congenital disabilities. Your ability to eat well and lose weight quickly affects your nutritional status. We strongly recommend pregnancy for two years after obesity surgery.

Back To Work:

When you can return to work depends on your general health and physical condition before the operation. Many patients return to work two weeks after surgery without any activity restrictions. However, some people need an extra two weeks. Full returns vary for each person and usually lasts about six weeks.


Patients with weight loss surgery, (after being approved by the surgeon for weight loss), must start a controlled program with low-impact exercise. Many bariatric patients cannot exercise before surgery, and some move to some extent due to being overweight. Regular exercise stimulates metabolism and thus helps with additional weight loss. Also, constant and medium training offers the following other benefits:

  • Increased endurance, balance, and flexibility
  • Reducing the risk of many diseases and
  • An improved overall sense of well-being.

It is beneficial that bariatric patients who begin a consistent exercise program reduce their chances of losing focus on the goals of the exercise. Here are some tips for staying up to date:

  • Set goals and track through the application or website,
  • Keep your training time constant,
  • Training with a partner or coach,
  • Join the gym,
  • Imagine a support group for bariatric operations

Lifestyle Changes:

As you underwent major surgery to achieve weight loss and a healthy body mass index (BMI), that was a great decision, and now you are committed to a new way of life. We hope the exercises you did earlier before operation, and calorie counting should become routine in your life.

Every day should be a reflection of the new change which is important to your health. Every day take pride that you keep this commitment for yourself. Participate in hobbies, activities, and groups. Visit a local weight loss or obesity support group regularly. The key is to stay busy with as many events, behaviors, and groups as possible to remind you of weight loss goals and promote your new lifestyle.

Long-Term Follow-Up with Surgeon:

The long-term effects of bariatric surgery should be under study by a doctor. Over time, malnutrition can occur. Routine blood tests are needed to ensure a balanced nutritional balance. We recommend that you do a series of tests every three months in the first year and then do annual examinations for the rest of your life.

Besides CBC, maintain other tests measure levels of alanine aminotransferase (ALT), albumin, alkaline phosphatase, aspartate aminotransferase (AST), calcium, cholesterol, direct and total bilirubin, electrolytes, glucose, ferrite, folic acid, hemoglobin A1c, saturation and iron transport, Magnesium, phosphorus, complete protein and vitamin B12. You may need to undergo tests to measure your Thiamine and vitamin D levels.


Dietary guidelines limit calorie consumption and provide balanced food to avoid nutritional deficiencies and to protect muscle tissue. Each patient tolerates the food offered differently.

Daily calories must be between 800 and 900 for at least the first 2 months after surgery and must not exceed 1000 calories per day. Follow a low calorie, low fat, and low sugar diet. Your goal must be at least 65 to 75 grams of protein per day. High protein foods include eggs, meat, fish, seafood, tuna, poultry, tofu, milk, soybeans, cottage cheese, and yogurt. Don’t worry if you don’t achieve this goal in the first few months after surgery. You will be most successful if you record your food and calories every day and follow a nutritionist regularly.

Here are some food guidelines to follow after the surgery:

  • Eat slowly and chew with small bites.
  • Avoid rice, bread, raw vegetables, fresh fruits, and non-hard meats like pork and steak. Minced meat is usually better tolerated.
  • For soft and solid food, take only three bites per session, and then wait at least 20 minutes before eating more.
  • Eat balanced meals in small portions.
  • Avoid using straws and carbonated drinks, chewing gum and ice, because it can carry too much air into your stomach and cause discomfort.
  • Avoid sugary foods and drinks, candy and concentrated fruit juices
  • Alcoholic beverages have a stronger effect and must be avoided or consumed with caution.

Over time, increase the variety and consistency of food in your diet. Some foods, such as red meat, chicken, bread, high-quality fruits, and vegetables, may initially be poorly tolerated. It will increase over time. It’s essential to be well hydrated. You should drink about 1.5 to 2 liters of fluid every day unless your condition shows other limitations.


Gastric bypass surgery can give you a new start for your health and fitness. Following a pre-surgery diet will then make a significant contribution to your success. Proper nutrition and lifestyle changes can protect you from surgical complications and teach you how and what to eat and drink for the rest of your life.
