If you\u2019re one of the millions of people with <\/span>diverticulitis<\/span><\/a>, you already know that taking control of your diet is key to managing your condition. You might think that taking vitamins will boost your overall health, but certain supplements could actually make your symptoms even worse.\u00a0<\/span><\/p>\n

There are four vitamins you should take with caution if you have diverticulitis, and a handful of tips you can implement to mitigate the risk of a flare-up.<\/span><\/p>\n

You can\u2019t talk about diverticulitis without talking about the colon. A healthy colon wall is smooth. Occasionally, the colon develops a small, irregular pouch that bulges. This pouch is called a diverticulum (multiple pouches are diverticula). The bowel wall can have weak spots in the wall of the large intestine. Risk factors for developing diverticuli are chronic constipation and increasing age. Chronic constipation stresses those weak spots and causes outpouching of the bowel and bulges.\u00a0\u00a0<\/span><\/p>\n

In fact, roughly <\/span>30% of people older than 50<\/span><\/a> have it. However, when the diverticula become inflamed, diverticulitis develops. This can lead to nausea, fevers, bloating, severe abdominal pain, constipation, and diarrhea. Some people experience acute bouts of diverticulitis, while others have it chronically.\u00a0<\/span><\/p>\n

Vitamins may not necessarily worsen diverticulitis, but rather, they can lead to additional gastrointestinal issues, and nobody wants to deal with that. Certain vitamins and supplements are linked to GI disturbances, and they can adversely affect you in the following ways:<\/span><\/p>\n
