Can diverticulitis cause weight loss?

My gastroenterologist told me that weight loss is very common during diverticulitis flares. This happens because of a combination of low appetite, nausea, and the temporary liquid diet required to let the colon rest. He advised monitoring weight closely to avoid severe weakness.

I lost quite a bit of weight during my last flare-up because I could only digest simple rice kanji (moong dal khichdi water). It's hard, but don't force heavy food. Once the pain settles, your appetite will return and you will recover your strength.

It's normal to lose some weight when you're dealing with colon inflammation since your calorie intake drops significantly. Don't worry about losing muscle or fitness progress right now. Focus entirely on recovering, and you can get back to your routine later.

With any gut issue, our absorption of nutrients decreases, which can lead to unexpected weight loss. Since our bodies are already sensitive to hormonal changes, please be gentle on yourself. Focus on simple, easily digestible foods and check in with your doctor.

I was reading up on this because my uncle has been losing weight recently and was diagnosed with diverticulitis. It seems very common because of the strict diet they have to follow during the painful phase. Glad to find some reassuring answers here.

I had a severe flare last year and lost 8 kgs rapidly because I couldn't keep food down. If you are experiencing sudden, rapid weight loss along with high fever or severe abdominal pain, please see a doctor immediately to prevent any serious complications.
