It takes a long time for the tiny coral polyps to create an entire reef. Coral formations grow an average of 1 to 8 inches per year. While ancestors of today's coral date back 240 million years, today's reefs began growing more than 50 million years ago, although most reefs are about 5,000 to 10,000 years old.hile ancestors of today's coral date back 240 million years, today's reefs began growing more than 50 million years ago, although most reefs are about 5,000 to 10,000 years old.
Esophageal motility disorder. An esophageal motility disorder is any medical disorder causing difficulty in swallowing, regurgitation of food and a spasm-type pain which can be brought on by an allergic reaction to certain foods. The most prominent one is dysphagia.
Risk factors for infectious esophagitis often relate to medications, such as steroids and antibiotics. People with diabetes also are at increased risk of candida esophagitis in particular. Other causes of infectious esophagitis may relate to poor immune system function. This may be due to an immune disorder, HIV/AIDS or certain cancers. Also, certain cancer treatments and drugs that block immune system reactions to transplanted organs (immunosuppressants) may increase the risk of infectious esophagitis.
