Two weeks after a colonoscopy, most issues like bloating or mild cramping are gone, but you should watch for signs of delayed complications, primarily bleeding (especially if polyps were removed, potentially heavy rectal bleeding/black stools) or infection/perforation (severe pain, fever, vomiting, chills, distended belly), which are rare but serious and require immediate medical attention. Any concerning symptoms, particularly significant bleeding or worsening pain, warrant a call to your doctor or emergency services.
Rare but serious complications can include colon perforation, infection, persistent bleeding, or allergic reactions to anesthesia. Medical attention should be sought for severe pain, vomiting, heavy bleeding, breathing issues, or infection symptoms such as fever or chills.
Most individuals can resume light activities, such as walking or working from home, on the same day of the procedure, depending on how they feel.

One study found that 40% to 45% of individuals experienced a range of symptoms, including abdominal bloating, abdominal pain, and dyspepsia, within 7 to 30 days after colonoscopy.

The most common side effects of colonoscopy are bloating and abdominal pain, though back pain can occur. The good news is that this type of discomfort or ache is almost always temporary. After a day or so, you should feel better.
Patients with post-polypectomy electrocoagulation syndrome typically present within 12 hours following a colonoscopy with fever, tachycardia, and generalized abdominal pain. However, the onset of symptoms may be delayed by up to 5–7 days after the procedure (2).

Bowel preparation for colonoscopy can lead to transient changes in the gut microbiota, potentially affecting an individual's health, especially in vulnerable populations, such as patients with inflammatory bowel disease. However, measures such as oral pro biotics may ameliorate these adverse effects.
Symptoms of a bowel perforation include:

Combining this with hydration and fiber is key for regularity.
Inflammatory bowel disease (IBD) includes Crohn's disease and ulcerative colitis. IBD causes symptoms like belly pain and cramps, diarrhea and blood in your poop (stool). Inflammatory bowel disease is chronic and can't be cured. There are treatments that can put the disease into remission but IBD often comes back.
