Smoking
Chemicals in cigarettes like nicotine greatly increases the risk of getting diverticulosis. Smokers are more liable to undergo sigmoidectomy [5] at a younger age than those who don’t smoke. Smoking greatly affects the digestive tract in general and does a lot of damage to its internal organs.
When diagnosing or treating diverticulosis, it is important that you avoid smoking completely.
Genetics
Diverticulosis is also hereditary. According to Oxford academic’s [6] family and twin studies, genetics may account for about 40-53% of the disease cases. This is not a leading cause of diverticulosis as other factors should be checked first. However, it is possible that a family member, especially a twin, having this condition may be the reason you have it.
Use of Certain Medications
The use of drugs like aspirin, ibuprofen, and steroids, which are nonsteroidal anti-inflammatory drugs (NSAIDs) may cause diverticulosis. Therefore, when checking for this condition, look out for the kinds of drugs you’re using and have been using.
