The controversial subject of drinking post-WLS

Alcohol bariatric surgery WLS


Alcohol has always held a stigma, but this is especially true when it comes to bariatric surgery.

Some of us are told we’re not supposed to drink at all after weight loss surgery, others hear they should take a six-month break. 

You are more sensitive to the effects of alcohol following bariatric surgery. This is because most absorption of alcohol occurs in the small intestine. If your stomach can’t break as much of the alcohol down, more of it will be absorbed by your system. Meaning, alcohol will affect you a lot more quickly and intensely than before.

The best way to monitor this is to increase self-awareness regarding your alcohol consumption – note how you feel after small amounts and regularly check in with yourself. Make sure to take breaks often and monitor how your body is reacting.

A small percentage of people will transfer their food addiction to alcohol after weight loss surgery. If you’re having trouble with this, you’re needn't feel alone or ashamed. Plus, there are some awesome people who can help you!

Side note - We’re at greater risk of developing a Vitamin B5 (aka Calcium Pantothenate) deficiency after WLS because of our extreme restrictive diet, and if we drink too much alcohol.

Speak with your GP if you notice symptoms like fatigue, depression, irritability, insomnia and muscle cramps and have regular blood tests.
