Micronutrients & recovery
Thiamine (Vitamin B1) deficiency is a medical emergency in bariatric patients presenting with rapid weight loss, vomiting, or neurological symptoms, requiring immediate treatment without waiting for blood test results.
If you have had bariatric surgery and experience severe vomiting, rapid weight loss, or confusion/numbness, tell your doctor immediately. They may give you high-dose thiamine (Vitamin B1) right away, even before blood tests come back, to protect your brain. This is a critical safety step.
If the patient presents with rapid weight loss, poor dietary intake, vomiting, alcohol abuse, oedema or symptoms of neuropathy, initiate treatment for thiamine deficiency immediately. Do not delay pending blood results.
