Man suffering from heartburn in Southaven MS

Case Study- Heartburn 

Did you know that studies show that up to 15% of individuals have heartburn at least once a week and about 7% have heartburn daily, so heartburn is one of the major challenges in family medicine. Heartburn is characterized by burning retrosternal discomfort. When severe, it may radiate to the sides of the chest, the neck, and the angles of the jaw. Heartburn is a characteristic symptom of reflux oesophagitis, which is a complication of gastro-oesophageal reflux. Gastro-oesophageal reflux disease (GERD) is one of the most prevalent gastrointestinal disorders.

Common Colonoscopy Myths

Myth #1 Colonoscopies Hurt

With today’s technology, the notion that a colonoscopy will be painful is simply not true. During a colonoscopy at Delta Gastroenterology, patients are very comfortable during the procedure – you should not expect any pain 

Myth #2 You Can Have A Colonoscopy Without Having To Prepare For It 

The colonoscopy procedure requires a certain amount of preparation prior to the day of the procedure.

Myth #3: Only older people need to have a colonoscopy

It’s true that colonoscopies are recommended for men and women 50 and older, but this age range changes if a patient has certain risks for colon cancer. An “at risk” patient includes someone with a family history of colon or colorectal cancer, as well as a person with a personal history of colon polyps, ulcerative colitis, Crohn’s disease, uterine or breast cancer.
