8 Things You Need to Know About Bariatric Multivitamins for Post-Surgery Health

One of the most important decisions a person can make is whether to have weight loss surgery, such as a gastric bypass. As patients gradually restore the quality of life that was lost due to being overweight, it is not only a life-altering commitment but also a practice that will add years to your life. Multivitamin use can aid in the treatment, cure, or avoidance of further issues that might develop in this case.
What are bariatric multivitamins?
Due to their decreased food intake following bariatric surgery and their bodies' reduced ability to absorb important nutrients, people who have had gastric sleeve and gastric bypass surgery sometimes suffer from malnutrition. Doctors advise vitamin and mineral supplements to help bariatric patients overcome this obstacle, but only if they are properly made for them. Such multivitamins that are easily digestible by bariatric patients post-surgery are called bariatric multivitamins.
Let’s break down some important things you need to know about these medicines:
1. You need medications right after surgery:
During the first three months following surgery, tablet drugs must be broken up or crushed; however, capsule, chewable, and liquid medications can be taken right away. By doing so, drugs are kept from being lodged in the digestive system or being incompletely absorbed.
Unless instructed otherwise by your pharmacist, resume taking your regular medications for any other conditions after surgery. After surgery, we advise you to follow up with your primary care physician and other specialists on a regular basis because rapid weight reduction may require frequent changes to medications, including those for diabetes and high blood pressure.
2. Difference between regular multivitamins and bariatric supplements:
Bariatric patients have different nutritional needs from a normal person. Before surgery, bariatric patients were eating enough to meet their nutritional needs for vitamins and minerals. They consume a lot less food after surgery, yet they still burn a lot of stored fat for energy. If their particular needs aren't satisfied, this could lead to malnutrition.
The vitamins and minerals that are lost due to dietary changes during bariatric surgery are specially replaced by bariatric vitamin supplements. These unique vitamins are easier to absorb in the shorter digestive tract and make up for the deficiencies in the diet. Patients who have surgery can continue to lose weight and retain their quality of life by taking these particular vitamins.
3. Help with maintaining weight loss:
Weight loss surgery may shock the body. The body must undergo significant changes in how it breaks down food and generates energy over the following few months, in addition to the stress caused by the operation and the recuperation period. Minerals and vitamins are necessary for both this process and the prevention of any diseases that malnutrition may cause.
Specifically, the body needs vitamins and minerals to assist in burning fat in order to produce energy. When a patient is deficient in particular nutrients, their progress may stall, and they may become discouraged. Just by taking bariatric vitamins, eating a balanced diet, and following recovery protocols, patients can experience sustained weight loss without experiencing sluggishness or halted fat loss.
4. You need calcium:
The daily calcium requirements following a gastric bypass or sleeve gastrectomy range from 1,200 to 1,500 mg. Following a duodenal switch, you require 1,800–2,400 mg of calcium daily. Food-based calcium contributes to your daily target. You should modify your supplemental calcium intake if your diet is heavy in the mineral.
Only 500–600 mg of calcium can be absorbed by your body at once. Take your vitamins in three separate doses throughout the day to improve absorption. The ideal medication form is calcium citrate. Consume calcium with food.
5. Common supplement needs:
Compared to standard over-the-counter multivitamins, bariatric vitamins differ in a few significant ways. In addition to the additional medical care required, bariatric patients require supplements such as:
-
Calcium: Bariatric vitamins are higher in calcium than ordinary vitamins, which is a typical deficiency in bariatric patients.
-
Iron: Since iron and calcium supplements hinder absorption, many physicians advise taking them at various times.
-
Vitamin B12: Deficiency can result in a variety of issues because vitamin B12 is an essential enzyme for energy synthesis and cell growth. B12 is abundant in bariatric supplements to help avoid deficits.
- Folate: Red blood cell formation requires folate, and restrictive diets frequently result in deficits.
6. Vitamin D3 is important:
You will require 75 micrograms, or 3,000 international units, of vitamin D3 daily. To find out if you are getting enough vitamin D, add the vitamin D content of your calcium and multivitamin pills. If not, you might want to think about taking another vitamin D3 supplement.
7. Focus on a nutrition-rich diet:
Dietary recommendations aim to provide balanced meals while restricting calories to prevent nutritional deficits and maintain muscle tissue. Remember that every patient has a unique food tolerance, so take this into account when making recommendations.
For at least the first 12 months following surgery, you should consume 500–700 calories per day, with no more than 1,000 calories per day. Adhere to a well-planned diet that is low in sugar and carbs and high in veggies and protein. A minimum of 60 to 80 grams of protein per day should be your aim. Eggs, meats, poultry, seafood (including tuna and other fish), tofu and other soy products, milk, cottage cheese, and Greek yogurt are examples of foods high in protein.
8. Include exercise in your routine:
Try to get in 30 to 45 minutes of aerobic exercise (often known as "cardio") three to five times a week. Walking for five minutes in the morning and five minutes in the afternoon is how we advise beginning. As acceptable, gradually extend these intervals by five minutes until you are walking for at least fifteen minutes twice a day. Following that, you can vary your schedule by swimming, mild jogging, or riding a stationary bike.
Vitamin recommendations for different types of patients:
-
Gastric bypass: Patients undergoing gastric bypass surgery are advised by their doctors to take a comprehensive multivitamin, calcium with vitamin D, iron, vitamin C, vitamin D, and vitamin B12.
-
Gastric Sleeve: Take a full multivitamin, calcium with vitamin D, iron, vitamin C, vitamin D, and vitamin B12 if you have gastric sleeve surgery.
- Gastric Band Surgery: Patients undergoing gastric band surgery are usually advised to take a full multivitamin, calcium, and vitamin D.
Adopting a healthy lifestyle post-surgery:
You have decided to have major surgery to help yourself reach a healthy body mass index (BMI) and lose weight. You must now make a commitment to a new lifestyle in which the habits you establish in the early post-operative period, such as regular exercise and calorie counting, become ingrained throughout your life.
We recommend seeing every day as an expression of a new mindset that your health is vital and that you are valuable. Celebrate each day that you stay true to this self-commitment. Participating in social groups, hobbies, and favourite activities that support your new lifestyle and serve as a reminder of your health goals is essential for success. Attend the bariatric or weight-loss support group in your community regularly.
Conclusion:
Bariatric multivitamins are essential for post-surgery health because they give your body the nutrients it needs for recovery, vitality, and long-term health. Their customized formulations tackle the particular complication of absorbing nutrients following weight loss surgery, and following a prescribed supplementing schedule is essential to preserving your health. Working closely with your bariatric care team and being aware of these eight important facts can help you avoid inadequacies and reap the maximum benefits of your surgical experience.
