A recent research conducted at the Mayo Clinic in Rochester, Minnesota has concluded that obese patients can consider bariatric surgery for reducing the risk of adverse cardiovascular events. This is the first ever study to take into account validated scores for cardiovascular risk on a patient population and compare them with previous results. The results showed that cardiovascular risk was reduced by up to 79 per cent.

Researchers are studying the case of a 27-year-old woman who developed a vitamin deficiency after failing to take multivitamins post- gastric bypass surgery. After two months of an uncomplicated surgery for weight loss at the University College Hospital, London she suffered from dizziness, vomiting and low-appetite. Also, prescribed lansoprazole (drug for prevention of acid production in stomach), the patient was found to be deficient in these medications. Only after physicians administered thiamine (Vitamin B1), the patient recovered.

According to American researchers, bariatric surgery patients with two obesity-related genetic variations are more likely to be obese compared to others. Published in the journal, Archives of Surgery, researchers analyzed patients’ blood samples for two common single nucleotide polymorphisms (SNPs) that are known to be connected with obesity. The research may offer new hope for patients who do not lose weight even after undergoing bariatric surgery.
