GERD

What is gastroesophageal reflux disease? How does it happen?


Gastroesophageal Reflux Disease (GERD) means the disease with the symptom that comes from the abnormal flow back of acid or digestive juice in the upper esophagus, which can occur in the afternoon or at night. The symptom might occur from irritation, which might be esophagitis with wound or esophagitis without wound. If the acid flows back above the sphincter of the upper esophagus, it might cause atypical or extraesophageal GERD. For example: Lung or throat symptom and Laryngophryngeal Reflux (LPR).



Normally, the body will have the mechanism to prevent the flow back of acid in the stomach and above in the upper gastrointestinal tract system. For example: The constriction of esophagus from top to bottom, and the function of sphincter of upper to lower esophagus. The membrane of esophagus has the mechanism to prevent the destruction from acid.



For the cause of GERD, it is believed that the sphincter of lower esophagus is abnormally loose, which causes the flow back of acid into the esophagus. Normally, if GERD flows back to the pharynx, it will stimulate the sphincter of upper esophagus to shrink in order to prevent the GERD from flowing back. It is believed that the preventive system of patient with atypical or extraesophageal GERD has malfunctioned so the GERD can flow back into the pharynx, larynx, and lungs.

Ovarian Cysts: A Hidden Threat Every Woman Should Know

These days, who would have thought that “ovarian cysts” would become a silent danger women need to be aware of? What’s even more concerning is that ovarian cysts often present no clear warning signs. Many women may be unaware that they have an ovarian cyst until they experience severe symptoms such as intense menstrual cramps, irregular periods, abdominal bloating, noticeable lumps in the pelvic area, or severe pain during intercourse. If left untreated, this condition can potentially be life-threatening. Unveiling the Secrets of Ovarian Cysts with a Specialist Professor Emeritus Dr. Sangchai Preutthipan, a specialist in reproductive medicine and laparoscopic surgery from Praram 9 Hospital, explains that the “ovaries” are small, thumb-sized organs responsible for producing eggs each month. With each ovulation, a fluid-filled sac forms around the egg. Sometimes, these sacs don’t dissolve as they should, leading to cyst formation. There are several types of ovarian cysts, including those caused by ovarian dysfunction, tumor-related cysts, endometriosis cysts (also known as chocolate cysts), cysts resembling other body tissues, and even cancerous cysts. Dr. Sangchai further notes that women of reproductive age up until menopause are at risk for ovarian cysts. Around 30-35% of women develop cysts due to ovarian dysfunction, while 20% develop tumor-related or chocolate cysts. Approximately 15% may have cysts that resemble other tissue types, and 1-5% are diagnosed with cancerous cysts. Each type of cyst carries different health risks.
