Bariatric vitamins exist for a reason. When your body lacks sufficient nourishment, you’ll often notice side effects. After weight loss surgery, every single nutrient becomes vitally more critical.

Weight loss surgery changes the way your gastrointestinal system works as well as the level of vitamins and minerls in your body. Not taking bariatric-specific vitamins after gastric bypass and gastric sleeve regularly can cause permanent memory loss and nerve damage.

So, what happens if you don’t take proper vitamin supplementation and minerals post-bariatric surgery? I am glad you asked.

Signs of Vitamin Deficiency

Feeling tired and cranky is the first indication of a vitamin-deficient diet. If a strict vitamin regiment is not followed, your body will send these red flags:

To sustain a healthy diet, you must take bariatric-specified vitamins after weight loss surgery to prevent detrimental consequences.

Taking dietary vitamins daily will help your body heal while still losing weight. Your stomach is very sensitive and won’t be able to handle vitamins in pill form for the first few months.

Drinkable and chewable vitamins can be easier to consume after bariatric surgery. After three months, you are more than welcome to take your vitamins in pill and capsule form.

Vitamin Requirements

The best way to maintain a well-balanced post-op diet is to follow the required dosages according to the American Society for Metabolic and Bariatric Surgery (ASMBS) guidelines:

Bariatric Multivitamin – Daily
Thiamine – 12mg
Zinc– 15mg
Calcium – 1,200-1,500mg
Vitamin D – 3000 IU (75mcg)
Iron – 45-60mg (menstruating women)

    • 18mg (Non-menstruating women)
    • 18mg (males with no history of anemia)

Vitamin C – 500mg
Vitamin B12 – 500-1,000 mcg sublingual pill

Good combinations

Some specific vitamins do not mix well with one another. For instance, it is required to take Iron and Calcium separately because they counteract each other and can hinder the absorption of Iron if taken at the same time.

  • Calcium Citrate with Vitamin D: Vitamin D aids calcium absorption in the body.
  • Iron with Vitamin C: They complement one another and are best absorbed in the body. Vitamin C helps absorb iron into the body.

Gummy Vitamins

Gummy vitamins are budget-friendly, but you need to research and find the best quality vitamins for your body. Quality matters. These vitamins are full of artificial food dyes, fillers, and preservatives. These vitamins are convenient but not always nutritionally beneficial. The disadvantages include added sugars, artificial sweeteners, and citric acid, which is detrimental to the enamel.

Why should I take Vitamins After Bariatric Surgery?

Let’s dive into the repercussions you are more likely to experience if you do not take the right vitamins after weight loss surgery.

What Happens If You Don’t Take Your Vitamins After Bariatric Surgery Mexico Bariatric Surgery Vitamin B1 deficiency

1. Thiamine Deficiency

Nausea and vomiting are common after gastric sleeve and gastric bypass surgery. Vitamin B1/Thiamine helps relieve nausea and vomiting issues. Healthy foods that contain Thiamine include legumes (chickpeas, lentils, beans), whole grains (brown rice, quinoa, buckwheat, and oats), and salmon.

Symptoms include nerve damage, loss of appetite, fatigue, irritability, tingling arms and legs, blurry vision, brain fog, nausea, and vomiting.

2. Zinc Deficiency

Zinc is essential for boosting an excellent immune system. After surgery, it is crucial to take 15mg of Zinc daily to prevent nutritional deficiencies.

Wholesome foods that are rich in zinc include meat (beef, lamb, and pork), shellfish (oyster, crab, shrimp, and mussel), legumes (chickpeas, lentils, beans), seeds (hemp, pumpkin, squash, sesame seeds), nuts (peanuts, cashews, and almonds), dairy (cheese and milk), eggs, whole grains (brown rice, quinoa, and oats).

Symptoms include diarrhea, slow wound healing, the common cold, skin ulcers, weak immune system, skin rash, and vision problems.

3. Calcium Deficiency

Low calcium can cause low bone mass and risk for osteoporosis. Osteoporosis causes bones to become brittle and weak. It affects both men and women and commonly occurs when the creation of new bone can’t keep up with the loss of the old one.

It is natural to think of dairy when we think about calcium. But there are other sources of nutritious foods that are rich in Calcium. These include seeds (poppy, sesame, celery, and chia seeds), sardines and salmon, beans and lentils, leafy greens, and tofu. Dairy products such as milk, yogurt, and cheese are good sources of calcium. Otherwise, calcium supplements are a great option.

Symptoms include numbness and tingling in the fingers, abnormal heart rhythm, brain fog, extreme fatigue, lack of energy, sluggish feeling, lack of focus, and forgetfulness.

4. Vitamin D Deficiency

Nowadays, people rarely spend time outdoors. This has become a significant cause of ongoing Vitamin D deficiency worldwide. It is crucial to take quality supplements to avoid any deficiencies.

Symptoms include loss of bone density (a significant contributor to osteoporosis and fractures), muscle weakness, fatigue, depression, hair loss, bone/back pain, and slow wound healing.

5. Vitamin C Deficiency

Vitamin C can easily be found in lemons, kiwis, and oranges. It is difficult to get enough Vitamin C through a diet alone. You improve your immune system by incorporating quality vitamin C foods and immunity.

Symptoms include tiredness, fatigue, mood swings, and slow healing wounds. The more extreme sign is “scurvy,” which causes bruising, dental problems, dry hair, dry skin, and anemia.

6. Iron Deficiency

Iron deficiency, known as anemia, occurs when hemoglobin is low in your red blood cells. Anemia is more common among RNY bypass patients as there is less absorption of food nutrients. When you have anemia, your body can’t get the proper amount of oxygen. Iron-rich foods include; spinach, broccoli, shellfish, red meat, turkey, legumes, quinoa, pumpkin seeds, tofu, and tuna.

Symptoms include fatigue, weakness, pale skin, cold hands and feet, headaches, irregular heartbeat, brittle nails, shortness of breath, and a tingling sensation in the legs.

What Happens If You Don’t Take Your Vitamins After Bariatric Surgery Mexico Bariatric Surgery Vitamin B12 Deficiency

7. Vitamin B12 Deficiency

After a gastric bypass or gastric sleeve, you do not produce enough gastric acids or intrinsic factor (IF) to absorb vitamin B12 properly. Both stomach acid and IF work to release B12 from food and assist with the absorption of the vitamin. For this reason, a B12 supplement is needed.

It is challenging to get enough vitamin B12 from foods that contain B12, such as beef, chicken, fish, etc. B12 is one of the most critical vitamins to take for the rest of your life because even people who consume enough meat are deficient in it.

Symptoms include irritability, lack of energy, fatigue, heart palpitations, depression, and headaches.

– Beri-Beri

Beri-Beri is a disease caused by Vitamin B1 deficiency (Thiamine). Individuals who drink an excessive amount of alcohol are more likely to be deficient in thiamine. A diet consisting of primarily white rice or highly refined grains can also lead to this.

Symptoms include trouble walking, loss of sensation in hands and feet, loss of muscle function, tingling, and vomiting.

– Wernicke-Korsakoff Syndrome

Wernicke-Korsakoff is a brain disorder caused by Thiamine depletion. It can stem from excessive alcohol use, eating disorders, vomiting, or chemotherapy. The brain’s thalamus and hypothalamus become impaired.

Symptoms include disorientation, nystagmus (a vision condition), and memory loss.
