Symptoms of lactose intolerance must appropriately defined so that you would be able to distinguish it from other types of gastrointestinal diseases. Diseases of the gastrointestinal system often present the same symptoms and would only differ in a manner of how long, to what extent and what group of symptoms takes place together. The symptoms of lactose intolerance must be appropriately pointed out so that corresponding treatment could be given.
Lactose Intolerance is defined as the problem in lactose digestion which is the sugar that can be found in milk. There is a lack in an enzyme known as lactase which has the abiltiy to break down and metabolize lactose from milk. This is often called lactase deficiency as well. Lactose intolerance has several types which include primary, secondary and congenital. Ingestion of dairy products leads to the appearance of different symptoms of lactose intolerance.
The symptoms of lactose intolerance are primarily gastrointestinal in nature because the mechanism actually happens in the stomach and some parts of the intestines. Some of the most common symptoms include abdominal pain, abdominal bloating, diarrhea, nausea, flatulence and even acid reflux.
First among the symptoms of lactose intolerance is abdominal pain which is usually experienced due to the inability of the stomach to digest the lactic content of the dairy product you just ingested. Due to the lack of enzyme, lactose is not absorbed by the body very well. Abdominal bloating deals with the feeling of fullness or having the feeling that your abdomen is like full of air or any other content. This is also known as abdominal distention and aside from the fact that you feel fullness, you can also feel the tightness of your abdomen. Diarrhea is the cause of frequent and often watery stools which can be brought about by faulty and impaired digestion due to the lack of enzyme that can properly metabolize dairy product contents primarily lactose.
Nausea involves the feeling of discomfort or uneasiness in the part of the upper stomach. When you are often attacked by the feeling of nausea, you would actually experience the urge to vomit accompanied by feelings of dizziness and weakness. Flatulence is often defined as the passage of excessive gas accumulated within the digestive system outside the body. The mixture of gases produced known as flatus is actually by products of the digestion process. Last among the symptoms of lactose intolerance, the acid reflux is defined as the back flow of acidic substances produced in the stomach to the esophagus which can cause burning pain known as heartburn. The reflux can also be attributed to the relaxation of the cardiac sphincter thus allowing the acidic of the stomach to flow back to the upper part of the digestive system.
These are the most common symptoms of lactose intolerance that you must be aware of. Once you experience one or more of them you must be alert enough and if you feel that they are really persistent whenever you are eating dairy products, think again and go for a check-up because you might no realize that you actually have lactose intolerance.
