After being diagnosed with a medical condition, it is important for patients to adjust their diet where necessary to prevent causing or exacerbating symptoms. Irritable bowel syndrome and diabetes are two conditions that are directly affected by what a patient includes in his diet. Irritable bowel syndrome, commonly referred to as IBS, is a medical condition that affects the large intestine. IBS is marked by bouts of constipation, gas and diarrhea. Type I diabetes is a form of diabetes characterized by the body's inability to create and sustain the necessary amount of insulin.
Consuming Fiber
Incorporating fiber into the diet can be beneficial for some people with IBS but problematic for others. IBS sufferers should experiment with fiber to determine whether it is helpful. If so, eating whole grains, fruits, vegetables and beans can provide good natural sources of fiber, according to MayoClinic.com. Some patients prefer taking a fiber supplement, such as Metamucil, rather than getting fiber from foods. Type 1 diabetes patients should eat whole grains, fruits and vegetables as a part of maintaining a healthy diet.
Maintaining Hydration
Water is an essential part of a healthy diet. Drinking an adequate amount of water helps prevent dehydration, which can lead to various health complications. It is generally recommended to drink at least eight 8 ounce glasses of water each day; more if a patient engages in exercise, is exposed to extreme heat or cold or is suffering from diarrhea. Drinking plenty of water can improve digestion and prevent gas and bloating. Avoiding caffeine and alcohol can reduce the likelihood of irritation in the intestines if a patient suffers from IBS. According to MayoClinic.com, alcohol can cause high or low blood sugar, and patients should consume it in moderation.
Managing Dairy Consumption
It may be necessary for patients with IBS to avoid dairy, especially if they are lactose intolerant. Some patients find that they can tolerate milk better than yogurt. Eating dairy may not cause or impact symptoms of type 1 diabetes. However, diabetes patients should limit their consumption of dairy products that contain high concentrations of fat. Eating too much fat can lead to weight gain, which can make diabetes symptoms worse.
Avoiding Symptom Triggers
It is important for IBS sufferers to avoid foods that trigger symptoms. Triggers vary by person. Some patients find they can eat small amounts of certain foods, while others find that their symptoms are most manageable when they avoid trigger foods completely.
