The intestinal mucosa of patients with ulcerative colitis and Crohn's disease is about one-third as thin as that of healthy individuals. Therefore, they are much more vulnerable to infection. This is why sometimes, when sharing the 'same food', 'only the patient' gets sick.
[Prohibited and Recommended Foods] The safest foods for ulcerative colitis and Crohn's disease patients are those that are cooked and heated immediately before eating, and those that are sterilized. Raw foods, raw fish (hoe), sushi, beef tartare (yukhoe), ice cream, etc., have a high possibility of containing bacteria and should absolutely not be eaten. Ready-made buffet foods or food that has been stored and sold are also high-risk.
[Lifestyle Rules] Picking up food with dirty hands, nail-biting, or thumb-sucking increases the risk of infection. Such infections occur frequently, especially in summer, so be sure to wash your hands thoroughly with soap often. If a patient with ulcerative colitis or Crohn's disease develops food poisoning or enteritis, abdominal pain and diarrhea will worsen, and bloody stools will increase. Recovery can take anywhere from 1-2 weeks to 1-2 months.
[Sudden worsening after improvement from herbal treatment] Sometimes, symptoms that were improving during herbal treatment can suddenly and rapidly worsen. Generally, sudden worsening after improvement is rare. However, occasionally, toxic bacterial infections such as Cytomegalovirus (CMV) or Clostridium difficile occur, worsening the symptoms. In cases of such viral or bacterial infections, it may look like ulcerative colitis or Crohn's disease are worsening, but in fact, it is often an infection unrelated to the underlying condition. If symptoms worsen rapidly during treatment, you must consult the clinic, and tests such as endoscopy, PCR, or bacterial toxin tests should be conducted at a hospital to rule out an infection.
