Lactose intolerance refers to an inability to properly digest lactose, a common sugar found in milk and other dairy products. Patients with lactose intolerance do not produce sufficient amounts of lactase, an enzyme that breaks down lactose into simpler sugars that can be absorbed into the bloodstream. This condition may develop as a result of genetic factors or after injury to the small intestine caused by other stomach issues. Breath testing is available to make a diagnosis.
After consuming lactose, patients often experience abdominal pain, bloating, gas or diarrhea 30 minutes to 2 hours later. Symptoms can range from mild to severe, depending on how much lactose was consumed and the sensitivity of the patient's individual condition. While there is no cure for lactose intolerance, patients can manage symptoms through simple dietary changes such as avoiding lactose and using lactose-free products. Your doctor can provide you with specific dietary recommendations.
Nausea & Vomiting
Nausea and vomiting are common symptoms that may be caused by a number of conditions. Some of these conditions include acute gastritis, signals from the brain, reaction from medication, obstruction of the bowel or another unrelated illness.
Acute gastritis is the most common cause of nausea and vomiting and is characterized by an inflammation of the stomach. Inflammation can be caused by an infection, stomach flu, food poisoning, peptic ulcer disease or other stomach irritants.
Relieving nausea and vomiting is usually done by treating the underlying cause of the symptoms. Resting the stomach by only consuming clear liquids can help ease the stomach back to a healthy state.
