Importance of Taking Vitamins and Minerals after Weight Loss Surgery

Weight loss surgery not only helps you shed excess weight; but also improves your health dramatically. Weight loss surgery is an effective and reliable treatment for severely obese people.

However, the surgery changes the way your body breaks down food and nutrients. Changes in stomach hormones and intestinal absorption are the common concerns resulting from weight loss surgery. Energy levels and mood can get altered due to the lack of vitamins after the surgery.

Proper nutrition is very crucial following weight loss surgery, which includes the need to take vitamin supplements every day without fail. The exact list and the precise amounts of vitamins vary from patient to patient, but every patient will require taking vitamins and minerals.

It is important to follow your doctor’s advice post weight loss surgery. Taking the proper nutrition appropriately will enhance your recovery results.

Here we discuss the importance of taking vitamins and minerals after weight loss surgery.

Nutritional Deficiency after Weight Loss Surgery

Bariatric surgeries alter the gastrointestinal tract to reduce the absorption or calorie intake that promotes weight loss.

The surgical alteration to the gastrointestinal tract restricts energy intake and also promotes malabsorption of nutrients depending on the manipulation of the GI system during the surgery.

All the magic happens in the small intestine. The majority of carbohydrates, fats, and proteins are digested in the small intestine. During the surgery, the small intestine gets compromised and this impairs the absorption of nutrients.

Moreover, nutritional deficiencies can also occur due to changes in stomach digestion and reduced food intake after weight loss surgery. Because of all these reasons, nutritional supplementation post-surgery is important for a healthy living.

Vitamin and mineral deficiencies can cause a wide range of health conditions. Therefore, doctors emphasize more on an adequate supply of vitamin and mineral supplements after weight loss surgery only to prevent any major adverse health conditions.

Importance of Taking Vitamins and Minerals

Vitamins and minerals are an essential part of general health and wellbeing. Vitamin and mineral deficiencies can cause a wide range of health conditions.

Therefore, doctors emphasize more on an adequate supply of vitamin and mineral supplements after bariatric surgery only to prevent any major adverse health conditions.

Moreover, it is reported that 75% of the weight loss surgery patients are already deficient in one or more vitamins before surgery.

Currently, there are a variety of bariatric multivitamins that contain all of the vitamins and minerals in one formulation. These maintain proper nutritional levels after weight loss surgery.

Proper vitamin and mineral supplementation will:

  • Enhance the immune system
  • Develop strong bones and teeth
  • Improve the development and function of the brain, heart, and nervous system
  • Promotes healthy skin and hair

Here are some of the best vitamins and supplements to prevent nutrient deficiencies after bariatric surgery and support overall health.

Bariatric Multivitamin

A bariatric multivitamin is a very essential part of life after weight loss surgery. These multivitamins contain higher doses of vitamins and minerals to fill the nutrient gaps caused by surgical alterations.

A typical bariatric multivitamin may contain

  • Vitamin – A, B1, B2, B3, B5, B6, B12, D3,E, K2
  • Biotin
  • Magnesium
  • Iodine
  • Folate
  • Zinc
  • Copper
  • Selenium
  • Manganese
  • Molybdenum
  • Chromium


Iron can be taken separately if it is not found in your bariatric multivitamin. It is usually recommended that weight loss surgery patients should take at least 18 mg of iron per day.

However, for an average person, taking a multivitamin with iron may not be beneficial as higher doses of iron could be dangerous.

Calcium Citrate

The most appropriate form of calcium for bariatric patients is calcium citrate. Since the restricted food intake post-surgery reduces calcium levels, it is important to consume calcium supplements after weight loss surgery.


A healthy gut is certainly a happy gut! Weight loss surgery often leaves patients with digestive issues. Probiotics are known to resolve these issues. Even research says that probiotics improve the GI symptoms after the surgery.

Gut bacteria that help in metabolism and maintaining appetite is also linked to support the weight loss programs, according to numerous studies.

The Last Word

Patients who decide to undergo weight loss surgery or have undergone should prepare themselves to incorporate healthy eating habits and regular physical activity to experience the most successful results.

As weight loss surgery is a permanent procedure, it is very crucial to make permanent diet changes to prevent nutritional deficiencies and stay healthy. We recommend these patients to consult a dietician or nutritionist to clarify all your queries about the post-surgical diet plan and the supplements.

With comprehensive long-term nutritional care, weight loss surgery patients will be able to maintain long-term weight loss and improve their quality of life.
