Food + bloating

Does milk cause bloating?

Short answer

Lactose is a clear testable suspectCow’s milk contains lactose. People who make less lactase may get gas, pressure or loose stool after a glass or milky coffee.

FODMAP readHigh

Regular cow’s milk is high in lactose at a cup-sized serving.

Two ways it can happen

01
Lactase breaks milk sugar into absorbable parts. When lactose remains, it can reach the colon and ferment.
02
Dose matters. A splash may sit well while a latte or milkshake crosses your threshold.

Portion changes the test

Track the amount as well as whether milk was present.
