Mild nausea is defined as the sensation of feeling the urge to vomit, but without actually vomiting. Bloating is defined as a feeling of fullness in the abdomen that may be accompanied by visible abdominal swelling. Mild nausea and bloating are among the most frequently reported digestive problems. Although mild nausea and bloating don't usually indicate a serious problem, occasionally these symptoms can signify an underlying condition.
Indigestion, which is also known as dyspepsia, is described as a combination of digestive symptoms that include extreme fullness during a meal, uncomfortable fullness after a meal and a burning pain that can travel from the lower abdomen to the upper abdomen. Mild nausea and bloating can also occur with indigestion. Indigestion usually occurs because of an underlying condition, such as gastroesophageal reflux disease, peptic ulcer disease or cancer, according to the National Digestive Diseases Information Clearinghouse. Occasionally, indigestion can occur independently. Treatment of indigestion consists of medications along with lifestyle changes, such as eating small meals throughout the day, cessation of smoking, avoiding coffee and alcohol and engaging in relaxation techniques such as yoga.
Gallstones are hard deposits that form in the gallbladder. The stones may be made of cholesterol or bilirubin and can range in size. It's not known exactly what makes gallstones form, but certain conditions can make gallstones more likely to form. These conditions include a malfunctioning gallbladder, liver problems, diabetes and rapid weight loss, according to MedlinePlus. When a large gallstone blocks the bile ducts, symptoms appear. These symptoms include pain in the abdomen, fever, jaundice, bloating and nausea. Gallstones may be dissolved with a series of medications or shock wave therapy. If this treatment isn't successful, surgery may be needed to remove the stones.
Gastritis is a condition characterized by inflammation of the stomach lining. It's most often caused by a stomach infection caused by the same bacteria that cause stomach ulcers, but it can also occur as a result of injury, chronic use of pain relievers or alcohol abuse, according to MayoClinic.com. Symptoms of gastritis include nausea, bloating, loss of appetite, belching, pain in the abdomen, feeling of fullness in the abdomen and weight loss. Gastritis can either be acute or chronic. Acute gastritis usually goes away on its own. Chronic gastritis is treated with a combination of antacid stomach medications and antibiotics.
