Dangers of Deficiencies After WLS

1 comment

When you are on a weight loss surgery journey, one of the most important things to look out for is vitamin deficiencies. Deficiencies can be extremely dangerous and need to be taken seriously.  As a bariatric patient, the two main deficiencies that can happen are vitamin B and vitamin D. However, there can be additional deficiencies as well. Calcium, folate, zinc, iron, and copper are also common deficiencies for bariatric patients. 

Vitamin D plays a huge role in maintaining healthy bones and it does this because it helps your body absorb calcium. Vitamin D is also essential for the health of our muscles and nerves and also aids in cell growth and function. Your body needs vitamin D to help your immune system stay strong. Vitamin D also plays a role in your mood, so when you are deficient you might feel a little down. 

Vitamin B1 plays a huge role in energy metabolism and is important for overall cell growth, development, and function. The body requires a continuous supply of vitamin B1 to keep yourself healthy. Vitamin B12 is key in reducing the risk of anemia. B12 also helps prevent fatigue and supports energy levels. When you are deficient in vitamin B, you might feel weak, tired and lightheaded. You might also experience heart palpitations and shortness of breath. 

In addition to the two main deficiencies, there are other vitamins to look out for as well. Calcium deficiency can cause muscle problems, nail and skin issues, and extreme fatigue. It can also lead to osteoporosis. Folate deficiency can have neurological signs, such as the feeling of pins and needles. Zinc, iron, and copper are also dangerous deficiencies. If you are a woman, iron is extra important for you to make sure you stay healthy. Zinc deficiency can cause diarrhea and altered taste, while a copper deficiency can cause issues with memory. 

All of these deficiencies need to be taken seriously after weight loss surgery. Your body is completely different and the way you absorb vitamins and nutrients is different. You must take the steps to ensure you stay healthy after bariatric surgery. The surgery is a wonderful tool, but it will not do all of the work for you. Finding a good routine with vitamins after surgery is necessary to keep yourself from experiencing dangerous deficiencies. If you are experiencing any symptoms, make sure you talk to your surgeon as soon as possible. Take control of your health and start a vitamin regimen today!

    I had the Gastric sleeve bypass surgery on 29th March 2017 and I crave sugar all the time. Is this normal? I don’t want to put the weight back on. Any advice?
