Are you lactose intolerant? Watch out for these 10 symptoms

Severe bloating

Lactose stays undigested in their gut leading to excessive gas production and uncomfortable abdominal bloating

Painful cramps

Undigested lactose causes muscle contractions in their intestines, resulting in sharp and painful stomach cramps

Diarrhoea

Water retention in the bowel due to  lactose fermentation causes loose stools  and sudden urges for toilet trips

Increases flatulence levels

Bacteria in the gut ferment undigested lactose, producing excess gas which leads to embarrassing flatulence

Skin breakouts

Some lactose intolerant people experience skin flare-ups and acne due to gut inflammation triggered by milk sugars

Sinus congestion

Indigestion

Lactose intolerance alters gut bacterial  balance causing further digestion issues  and reduced nutrient absorption

Nausea

Even small amounts of milk can trigger a strong sense of nausea and discomfort almost immediately after consumption

Chronic fatigue

Constant digestive distress and poor nutrient absorption leave lactose intolerant people feeling tired and energy-depleted
