Frequently Asked Questions

What time of day should I take bariatric vitamins?

Bariatric vitamins should be taken with meals throughout the day, as directed by your doctor or bariatric dietitian. Generally, it is best to take them with breakfast, lunch, and dinner.

It is important to take them with food since the best bariatric vitamins are fat-soluble and need to be taken with food for maximum absorption. Taking them with food will also help to reduce the risk of nausea or stomach upset.

What bariatric vitamins and other supplements should I take?

The vitamin and mineral supplements you should take after bariatric surgery depend on the type of procedure you had, your individual nutritional needs, and your lifestyle.

Generally, bariatric surgery patients should take a multivitamin, calcium and vitamin D, iron, vitamin B12, and omega-3 fatty acids.

Additional supplements may be necessary depending on your health needs. It is important to discuss your individual nutritional needs with your doctor to ensure you are taking the right vitamins and supplements for your health and lifestyle.

What is the difference between a bariatric supplement and a regular supplement?

The best bariatric vitamins and supplements are specifically formulated to address the nutritional needs of people who have undergone bariatric surgery or are following a bariatric diet. These supplements contain higher levels of essential nutrients such as protein, vitamins, and minerals, and are designed to help individuals meet their nutritional needs while following a low-calorie diet.

Regular supplements, on the other hand, are designed to provide general nutrition and may not be tailored to the specific needs of individuals who have had bariatric surgery or are following a bariatric diet.

What are the common weight loss surgeries?

The most common weight loss surgeries are Roux-en-Y gastric bypass, sleeve gastrectomy, and adjustable gastric banding.

Roux-en-Y gastric bypass involves creating a small pouch in the stomach and connecting it directly to the small intestine. This reduces the amount of food that can be eaten and absorbed, resulting in weight loss.

Sleeve gastrectomy involves removing a large portion of the stomach, reducing its size and capacity. Adjustable gastric banding involves placing an inflatable band around the stomach to reduce its size, restricting the amount of food that can be eaten.

All of these surgeries can help with weight loss, but they come with risks and side effects, so it is important to talk to your doctor before deciding whether or not to have surgery.

Are bariatric procedure vitamins necessary even if you eat a healthy diet?

Yes, the best bariatric vitamins are necessary even if you eat a healthy diet. Bariatric procedures can significantly reduce the amount of food you can eat, which can lead to a lack of essential vitamins and minerals in your diet.

Additionally, bariatric procedures can lead to malabsorption of essential minerals and vitamins, which can further increase the need for supplementation. Crucial Vitamin B12, for example, can only be absorbed in the body through supplementation after surgery for weight loss.

Taking a multivitamin and mineral supplement designed specifically for people who have had bariatric procedures is recommended to ensure you are getting the nutrients you need to avoid nutrient deficiencies.

Can bariatric patients use gummy vitamins?

Bariatric patients cannot use gummy vitamins because they contain sugar alcohols and other sweeteners that can cause digestive problems and discomfort.

Additionally, gummy vitamins are often not as complete or potent as other forms of vitamins, and may not provide adequate nutrition for patients after a bariatric procedure.

Weight loss surgery patients should instead opt for other forms of vitamins, such as capsules, chewable tablets, or liquid vitamins, which are better suited for their dietary needs.

What happens if you don't take vitamins after bariatric surgery?

If you don't take vitamins after weight loss surgery, you may be at risk for vitamin and mineral deficiencies. Bariatric surgery can reduce the absorption of certain vitamins and minerals, and without supplementation, you may not be able to get enough of these nutrients from your diet.

This can lead to a variety of health problems, such as anemia, osteoporosis, and nerve damage. Therefore, it is important to take a multivitamin and additional supplements as recommended by your doctor after bariatric surgery.

How can I prevent loose skin after bariatric surgery?

The best way to prevent loose skin after weight loss surgery is to ensure that you are losing weight at a healthy, gradual rate. Rapid weight loss can lead to more loose skin, as the skin does not have enough time to adjust to the changes in your body.

Additionally, it is important to maintain good nutrition and hydration in order to keep your skin healthy and elastic. Exercise can also help to improve skin tone and elasticity. Finally, be sure to keep your skin well-moisturized to help reduce the appearance of any loose skin.

What is dumping syndrome?

Dumping syndrome is a condition that occurs when food, especially sugar, moves too quickly from the stomach to the small intestine. This causes a range of symptoms including nausea, vomiting, abdominal pain, cramping, bloating, diarrhea, dizziness, sweating, and fatigue.

It is usually caused by surgery on the stomach or small intestine, such as gastric bypass surgery. Treatment usually involves dietary changes that involve eating smaller meals, avoiding sugary foods, and eating slowly.

Are vitamin patches effective for calcium supplementation post surgery for gastric bypass patients?

Vitamin patches are not recommended for calcium supplements post-surgery for gastric bypass. While vitamin patches can be effective for delivering all the nutrients of certain specific vitamins, the delivery of calcium to the body should be done orally or through injections.

Oral supplementation is the preferred method for calcium supplementation post-surgery for gastric bypass, as it is the most effective way to ensure that the calcium is absorbed properly. Additionally, supplemental calcium should be taken with food, as this helps the body absorb the calcium more effectively.

Which vitamins and other nutrients are poorly absorbed after bariatric surgery?

Bariatric surgery can lead to malabsorption of certain vitamins and minerals, including iron, calcium, vitamin B12, and vitamin D. In addition, vitamins A, D, E, and K are fat-soluble and can be poorly absorbed after weight loss surgery. Vitamin B12 is always going to have to be supplemented after weight loss surgery. The other B vitamins are not as tricky, but should be supplemented, as well.

In order to prevent deficiencies, it is important to take a multivitamin that contains at least 100% of the recommended daily allowance (RDA) for these vitamins and minerals.

It is also recommended to take additional supplements of iron, calcium, and vitamin B12, as these nutrients are especially difficult to absorb after bariatric surgery. Iron deficiency is a huge problem, especially for patients who have had a gastric bypass. It is not uncommon for iron deficiency to get so bad that these patients can require iron infusions in the hospital.

Why are fat soluble vitamins not absorbed well after bariatric surgery?

Fat soluble vitamins, such as vitamins A, D, E, and K, are not absorbed well after bariatric surgery because the surgery reduces the amount of fat in the digestive tract.

Since these vitamins are absorbed through fat, the reduced amount of fat in the digestive tract makes it difficult for the body to absorb these vitamins.

Additionally, the surgery can also reduce the production of bile, which is essential for the absorption of vitamins that are fat-soluble.

Therefore, it is important for people who have had bariatric surgery to take supplements to ensure they are getting enough of these vitamins.

Can bariatric patients chew gum?

Yes, patients can chew gum after a bariatric procedure. However, it is important to note that chewing gum can lead to increased hunger and cravings, so it is best to limit gum consumption to small amounts.

Also, it is important to choose sugar-free gum that does not contain any artificial sweeteners, as these can cause gastrointestinal issues. Additionally, gum should not be chewed for more than 20 minutes at a time, as this can lead to excessive swallowing of air, which can cause bloating and discomfort.

Is there anything you can never eat again after bariatric surgery?

Yes, there are certain foods that you should avoid after bariatric surgery. These include high-fat, high-sugar, and high-calorie foods, as well as foods that contain a lot of artificial sweeteners.

You should also avoid carbonated beverages, alcohol, and foods that are difficult to chew or digest, such as tough meats and raw vegetables.

It is important to follow the dietary guidelines provided by your doctor or dietitian after bariatric surgery to ensure that you get the nutrients you need while avoiding foods that could be harmful.

Why can't bariatric weight loss patients use a straw?

Bariatric patients are advised not to use a straw because it can lead to excessive air intake, which can result in stomach discomfort, bloating, and even vomiting. The suction created by the straw can cause air to be pulled into the stomach, which can then cause a distended abdomen and abdominal pain.

Additionally, drinking too quickly through a straw can lead to regurgitation of the beverage and can also cause the patient to swallow more air than normal.

Is there a form of calcium that absorbs best after bariatric surgery?

Yes, the best form of calcium to absorb after bariatric surgery is calcium citrate. Calcium citrate is a form of calcium that is more easily absorbed by the body than other forms of calcium, such as calcium carbonate.

It is also less likely to cause gastrointestinal side effects such as gas and bloating. Additionally, calcium citrate does not require the presence of stomach acid for absorption to get enough calcium, which is beneficial for people who have had bariatric surgery, as they often have decreased stomach acid production.

Why don't bariatric multivitamins contain calcium?

Bariatric multivitamins typically do not contain calcium because calcium is best absorbed when taken separately from other vitamins and minerals. Taking calcium with other vitamins and minerals can interfere with the optimal absorption of both, so it is usually recommended to take calcium supplements at a different time of day than other multivitamins.

Additionally, bariatric multivitamins are specially formulated to meet the unique needs of bariatric patients, and calcium is not typically included in these formulations.

How do you correct Vitamin Deficiencies Prior to Your Bariatric Surgery?

The best way to correct vitamin deficiencies prior to bariatric surgery is to work with your doctor to identify any micronutrient deficiencies and then supplement with the necessary vitamins.

It is important for most patients to start taking vitamins and any other supplements at least two weeks before the surgery to ensure your body has the best vitamins it needs for the surgery and recovery process without nutritional deficiencies.

Additionally, it is important to maintain a healthy diet and lifestyle as this will help ensure that your body has the vitamins and minerals it needs. Finally, it is also important to take a multivitamin daily to ensure your body is getting the necessary vitamins and minerals.

Is there a difference in the bariatric nutritional supplementation required for Gastric sleeve vs. gastric?

Gastric sleeve surgery is a restrictive procedure that reduces the size of the stomach and limits the amount of food that can be eaten at one time. Gastric bypass surgery is a combination of restrictive and malabsorptive procedures, which means that not only does it reduce the size of the stomach, but it also changes the way food is digested and absorbed.

Gastric sleeve surgery is often recommended for those who have a BMI of over 40 or for those who have a BMI of over 35 with a co-morbidity. Gastric bypass surgery is typically recommended for those who have a BMI of over 50 or for those who have a BMI of over 40 with a co-morbidity.

Both procedures require supplement needs to be met in order to avoid malnutrition. Supplements may include vitamins, minerals, proteins, and other nutrients. Your doctor or nutritionist can help you determine the best type and amount of supplements for you based on your individual needs.
