How heartburn and GERD occur Acid reflux occurs when the sphincter muscle at the lower end of your esophagus relaxes at the wrong time, allowing stomach acid to back up into your esophagus. This can cause heartburn and other signs and symptoms. Frequent or constant reflux can lead to GERD. Gastroesophageal reflux disease (GERD) occurs when stomach acid repeatedly flows back into the tube connecting your mouth and stomach (esophagus). This backwash (acid reflux) can irritate the lining of your esophagus. Many people experience acid reflux from time to time. However, when acid reflux happens repeatedly over time, it can cause GERD. Symptoms Common signs and symptoms of GERD include: • A burning sensation in your chest (heartburn), usually after eating, which might be worse at night or while lying down • Backwash (regurgitation) of food or sour liquid • Upper abdominal or chest pain • Trouble swallowing (dysphagia) • Sensation of a lump in your throat If you have nighttime acid reflux, you might also experience: • An ongoing cough • Inflammation of the vocal cords (laryngitis) • New or worsening asthma When to see a doctor Seek immediate medical care if you have chest pain, especially if you also have shortness of breath, or jaw or arm pain. These may be signs and symptoms of a heart attack. Make an appointment with your doctor if you: • Experience severe or frequent GERD symptoms • Take over-the-counter medications for heartburn more than twice a week Causes GERD is caused b...

The digestive organs in the abdomen work together to absorb nutrients and move food through the digestion process. They include the stomach, gallbladder, liver, pancreas, intestines, and urinary system. The digestion process is interdependent and a problem with one organ may disrupt the function of another. For example, Issues with the digestive organs can include pain, weight gain or loss, digestive problems, This article examines each of the digestive organs in the abdomen, how they work together, and common health problems. Share on Pinterest Yaja’ Mulcare The digestive organs in the abdomen do not work alone. They depend on organs in the mouth and chest, such as the esophagus and tongue, to help chew, move food, and perform primary digestive functions. The abdomen also includes the urinary system. The pelvis, the lower portion of the abdomen, contains reproductive structures. Food travels to the stomach from the esophagus. Once it arrives, the stomach helps digest food via contractions and chemical enzymes. The stomach has three layers: the oblique layer, the middle circular layer, and the external longitudinal layer, which breaks down food mechanically. Acids such as hydrochloric acid further digest food into a liquid substance called chyme. A network of cells — including parietal cells, chief cells, G-cells, mucous neck cells, and D-cells — help chemically digest food by secreting stomach acids. The stomach can also hold food until it moves further along the digestiv...

The Throat and Esophagus The throat (pharynx) lies behind and below the mouth. When food and fluids leave the mouth, they pass through the throat. Swallowing of food and fluids begins voluntarily and continues automatically... read more is the hollow tube that leads from the throat (pharynx) to the stomach. Food does not just fall through the esophagus into the stomach. The walls of the esophagus propel food to the stomach by rhythmic waves of muscular contractions called peristalsis. As a person swallows, food moves from the mouth to the throat, also called the pharynx (1). The upper esophageal sphincter opens (2) so that food can enter the esophagus, where waves of muscular contractions, called peristalsis, propel the food downward (3). The food then passes through the diaphragm (4) and lower esophageal sphincter (5) and moves into the stomach. Just below the junction of the throat and the esophagus is a band of muscle called the upper esophageal sphincter. Slightly above the junction of the esophagus and the stomach is another band of muscle called the lower esophageal sphincter. When the esophagus is not in use, these sphincters close so that food and stomach acid do not flow back up the esophagus from the stomach to the mouth. During swallowing, the sphincters open so food can pass to the stomach. With aging, the strength of esophageal contractions and the pressure in the sphincters decrease. This condition makes older people more prone to backflow of acid from the st...

A hiatal hernia is when your stomach bulges up into your chest through an opening in your diaphragm, the muscle that separates the two areas. The opening is called the hiatus, so this condition is also called a hiatus There are two main types of hiatal hernias: sliding and paraesophageal. Ordinarily, your A paraesophageal hernia is more dangerous. Your esophagus and stomach stay where they should be, but part of your stomach squeezes through the hiatus to sit next to your esophagus. Your stomach can become squeezed and lose its blood supply. Your doctor might call this a strangulated hernia. Hiatal Hernia Symptoms Many people with hiatal hernia don’t notice any symptoms. Others may have: • • Chest pain • Bloating • Burping • Trouble swallowing • Bad taste in your mouth • An upset stomach and • Backflow of food or liquid from your stomach into your mouth • Shortness of breath Get medical care right away if you have a hiatal hernia and: • Severe pain in your chest or belly • A persistent upset stomach • Vomiting • Can’t poop or pass gas These could be signs of a strangulated hernia or an obstruction, which are medical emergencies. Hiatal Hernia Causes Doctors don’t know why most hiatal hernias happen. Causes might include: • Being born with a larger hiatal opening than usual • Injury to the area • Changes in your diaphragm as you age • A rise in pressure in your belly, as from Hiatal Hernia Risk Factors Hiatal hernias happen more often in women, people who are overweight, an...
