Digestive Disorder Signs

Symptoms of gastrointestinal disorders differ among individuals. People can experience stomach pain, constipation, indigestion, or diarrhea. Anytime you have a new or unusual symptom, it’s a good idea to schedule an appointment with a primary care doctor so they can refer you to our specialists if needed.


Treatment varies depending on the digestive condition. Here are some of the most common treatment options.

  • Nutrition and Dietary Changes: Some digestive conditions can be improved by making changes to your diet. Your doctor may recommend eating healthier and increasing your exercise to keep your digestive system on track. They may also advise avoiding certain foods that may cause irritation. Doctors also suggest taking vitamin supplements or probiotics to provide nutrients to your system.
  • Medication: There is a wide range of medications and supplements for digestive conditions. Antibiotics, antacids, immune suppressors and anti-inflammatory drugs are commonly used to treat digestive conditions.

Surgery: In some cases, the best treatment option is surgery. Many procedures can now be done with minimally invasive techniques.
