Daily nausea may be caused by a wide range of illnesses and conditions. Among the most frequent causes of daily nausea are morning sickness, indigestion, and side effects of medication. In some cases, nausea may be caused by a chronic condition that affects the digestive tract. For example, a person may develop chronic nausea in relation to a peptic ulcer, which is a hole in the lining of either the stomach, the tube through which food passes to the stomach, or the small intestine.
For women, one of the most common causes of daily nausea is morning sickness. This condition is marked by nausea, and often vomiting, that occurs during pregnancy. It is most likely to occur during the first few months of pregnancy and may affect a pregnant woman at any time of the day, despite being called morning sickness. Some women find their nausea is worse when they haven’t eaten for a while, upon getting out of bed in the morning, when they consume large meals, and when they are exposed to certain smells. Morning sickness may also be caused by hormonal changes that are common during pregnancy.
Indigestion is also among the most common causes of nausea. Essentially, indigestion just means an upset stomach, and an individual may develop it after eating too slowly or too quickly. Sometimes a person may also develop it because he has eaten something that irritates his stomach. In some cases, a person who has indigestion may also have heartburn, which occurs when stomach acids move up from the stomach and into the esophagus, which is the tube through which food enters the stomach. Heartburn may cause nausea as well.
Medication side effects are also among the most common causes of nausea. There are many types of oral medication, prescription and over the counter, that are known to cause nausea in some people. If a person takes a medication on an empty stomach, he may be more likely to suffer from nausea as a side effect of medication. Some people, however, are just sensitive to medication and may experience nausea even if they take their medication on a full stomach.
Sometimes a chronic condition will be at the root of daily nausea, especially when the medical condition affects the gastrointestinal tract. For example, a peptic ulcer, which is a hole in the lining of a person’s stomach or esophagus, may cause nausea on a daily basis. A person with this condition may even have a hole in the lining of his small intestine. While some people may believe peptic ulcers are caused by stress or spicy foods, this is a misconception. Bacteria cause peptic ulcers in most cases, but stress can contribute to their development.
