What Are The Best Vitamins To Take After Bariatric Surgery

How Long Do I Need To Take Vitamins After Bariatric Surgery

Recommended Vitamins and Minerals Post-Bariatric Surgery

After bariatric surgery, vitamins fill in any nutritional gaps that might arise from the change in eating habits or from the procedure itself. As a bariatric dietitian, two of the most common questions I get asked from pre-operative patients is how long they will have to take vitamins and which ones they should take.

How Long to Take Vitamins

What I tell patients is that having weight loss surgery, whether its gastric sleeve or gastric , means there will always be a need for some type of nutrient supplementation. This is because a portion of your stomach, where vitamins and minerals are absorbed, is removed during the surgery causing your bodys needs to be greater. Taking a high quality multivitamin/mineral supplement and calcium will be important following surgery

At New Jersey Bariatric Center, we have postoperative patients do blood work at their 3 month visit after surgery. This is to check for healthy vitamin and mineral levels. In some cases, results may indicate that the blood levels of a supplemented nutrient are within the normal range and the supplement can be discontinued.

After the first year, annual blood work and a yearly visit with your surgeon is the best way to assess long-term nutritional status. Meeting regularly with your bariatric dietitian is another way to ensure all your nutrient needs are being met.

The Most Important Vitamins For Bariatric Patients

So what are the most important vitamins for bariatric patients? Since the body processes the vitamins differently after weight loss surgery, it is important to make sure that you are adding in certain vitamins and minerals. Specifically, you need to add iron, B12, calcium and vitamin D.

You should take a multivitamin daily. Look for one that has at least 18 mg of iron. Make sure you are getting 1500 mg of calcium a day to prevent bone density loss. To make sure you are getting the best absorption possible, split the dosage of calcium between 3 doses a day. Do not mix the calcium and iron together since iron can have an effect on calcium absorption. To make sure you are getting enough Vitamin D, you will want to take 800 to 1000 IU daily. It is best to take this in 2 doses and take them at the same time you take the calcium. You can also opt for a vitamin that is calcium and Vitamin D together. The last vitamin you want to make sure you are getting enough of is Vitamin B. You can take this as 500 mg daily or as a monthly injection.

Using Supplements After Gastric Bypass Surgery

surgery reduces the size of the stomach and reroutes the digestive system so that fewer nutrients are absorbed. You will need to pay very careful attention to what you consume after your surgery to make sure that you get the vitamins and minerals you need each day.

Taking a good multivitamin daily is one of the most important things you will need to do to maintain good health after weight loss surgery. Failing to keep up with that can lead to serious complications related to vitamin deficiencies. However, a multivitamin alone will not be enough to make up for nutrients you will no longer be getting from foods.

You should also supplement B vitamins. A B-1 deficiency can cause heart problems. It can also lead to a nervous system disorder known as beriberi. Symptoms include dizziness, nausea, vomiting and a loss of appetite. B-12 is also necessary. Many surgeons recommend that you take 500 micrograms of B-12 in a sublingual pill each day.

Anemia is common after weight loss surgery, and an iron supplement can help stave it off. Taking your iron supplement with orange juice or with an iron supplement can help your body absorb iron more efficiently.

Calcium helps protect bones against breakage. You should take 1200 milligrams each day. Take half of this in the morning and half at night. Do not take calcium supplements at the same time as iron, as calcium can keep iron from being absorbed properly.

Liquid Bariatric Vitamins Vs Chewable Bariatric Vitamins: Which One Is Good For Me

Vitamins can be tough on the stomach. Even the chewable bariatric vitamins can sometimes give people fits. But before you switch to a gummy vitamin, lets try a few other options.

Our concern with a gummy vitamin is the lack of complete vitamins and minerals. To make it still gummy manufacturing needs to eliminate lots of key minerals. The other concern is in the ingredients list. The first ingredient- sucrose.also known as sugar.

Vitamin And Mineral Supplements

Vitamins for Life: Taking Supplements after Bariatric Surgery

Vitamins and minerals are vital for appetite regulation, fat storage and metabolic rate so are important for good health, weight loss and long-term weight maintenance. After weight loss surgery, portion sizes are smaller, some food groups may not be tolerated and there may be reduced absorption of vitamins and minerals.

It is essential for all gastric sleeve patients to take vitamin and mineral supplements for life unless your surgeon has advised you differently. Failure to do so may lead to health problems.

Our Bariatric Nurse will discuss this with you during your pre-operative call. You need to start taking vitamins at week 3 and we recommend that you take a complete multivitamin and mineral, calcium, vitamin D, iron, and vitamin B12 in line with guidance from The British and Obesity Metabolic Surgery Society.

Why Do Bariatric Surgery Patients Have To Take Vitamins

Bariatric surgery changes the size of the stomach causing individuals to eat less, and since some techniques alter the digestive system, nutrients from foods that are ingested cannot thoroughly be absorbed. This decrease in absorption means that many vitamins, minerals, and micronutrients critically needed by the body are not being captured.

Which Vitamins Do I Really Need

Spring 2010

To view a PDF version of this article,

After weight-loss surgery, one of the things that most people have to adopt as a new habit is taking vitamins every day. While there are general things that might be the same between what your doctor recommends and what another doctor recommends, some things might be different.

When answering the question, What do I really need to take?, the first and most important answer is Take what your doctor recommends. Somewhere along the way, your bariatric surgeon, or the dietitian in the office, probably gave you a list of the vitamins you needed to take after surgery based on your procedure.

Also, if your doctor looked at your labs, you might have been given some very specific recommendations just for you. Either way, this is where you should start. If you have not seen your bariatric surgeon in many years, it is also wise to call the office and find out what the current recommendations are knowledge about nutrition has changed a lot in recent years and they might have new recommendations that you were not given.

Generally speaking, taking supplements after surgery is for three reasons:

  • To make sure you get adequate vitamins and minerals even though you are eating less food
  • To help prevent deficiencies that you are at greater risk for because of your procedure
  • In some cases, to treat a nutritional deficiency

The most common types of supplements taken after surgery are multivitamins, calcium, vitamin B12 and iron.


How Common Is The Problem Of Vitamin Deficiency After Gastric Bypass

What many dont realise, is that most patients, if not all, who undergo gastric bypass surgery will need to take vitamin supplements for the rest of their lives. Vitamin deficiency after gastric bypass is something experienced by almost 40% of all gastric bypass patients. Whether it be due to patients not adhering to the strict dietary and supplementation guidelines after surgery, or physicians not diligently checking their patients vitamin levels, the problem of vitamin deficiency after gastric bypass surgery is surprisingly very common.

What Is The Most Important Nutrient After Bariatric Surgery

Top Supplements After Bariatric Surgery | Blossom Bariatrics | Las Vegas

There are three very important components in proper nutrition after bariatric surgery:

  • Macronutrients are proteins, carbs, and fats that will be tracked using daily goals or limits.
  • Micronutrients: this is a big word that means vitamins and minerals, but unlike proteins, carbs, and fat, your body only needs a small amount of vitamins and minerals. Macro is a prefix that means large and micro is a prefix that means small. Do not be confused, however, thinking that because the body only needs a SMALL amount, those micronutrients are unimportant because a deficiency can cause BIG problems.
  • Water: after weight loss surgery, it is very important you remain hydrated because dehydration is the reason bariatric surgery patients most often re-enter the hospital. You will be tracking your daily liquid intake to ensure you are getting the recommended amount. Most bariatric doctors recommend carrying around a 64-oz container of water and sipping on it throughout the day, except for 30 minutes before and after meals.

How It Can Cause A Vitamin B12 Deficiency

In the stomach, theres a paper-thin layer called the gastric mucosa. This layer releases intrinsic factor that helps the stomach to absorb vitamin B12 from food. The new stomach pouch is so small that there is a decrease in gastric acid. When food is traveling through this small section of the stomach, the gastric mucosa is unable to provide enough intrinsic factor to allow vitamin B12 to be adequately absorbed.
