What are the most common causes of nausea in the afternoon?

There are many reasons for nausea in the afternoon, including caffeine consumption, lack of sleep, or illness. One of the most common causes of afternoon nausea in women is pregnancy. Nausea is the body's way of suppressing your appetite because something is wrong, usually in the digestive tract, blood sugar levels, or the center of balance in the inner ear. Center of balance problems can include ear infections or simple motion sickness.

Despite its name, morning sickness during pregnancy doesn't just happen in the morning. Afternoon nausea is often associated with pregnancy, especially in the early stages. If nausea in the afternoon or at night is something quite new and there is a possibility that a woman is pregnant, she can consult a doctor. Common treatments for this cause of nausea include home remedies such as chamomile or peppermint tea, sucking on hard candy, or simply lying down. Nausea that is severe and persistent during pregnancy may need treatment through a change in diet, or even medications that a doctor has prescribed or deems safe.

A low-calorie or high-sugar diet can cause nausea during the day, especially in a person who is more active. Blood sugar levels can become unbalanced throughout the day, especially in people with diabetes. Some proven ways to treat nausea due to diet problems include eating a small amount of bland, starchy foods, drinking water, or even taking herbal licorice or fiber capsules.

Other factors, such as stress, lack of sleep, and anxiety can cause nausea in the afternoon. A brain without enough rest can become more susceptible to internal and external changes, causing symptoms such as nausea, irritability, or even hallucinations. Just as a brain under undue stress or anxiety may be less able to process and function properly, a tired brain may develop these same problems.

In the case of motion sickness, the center of balance within the inner ear becomes confused by the signals it is receiving. For example, when reading in a car, a person's eyes may be fixed on the book, but the fluid in their ears moves with the car. This type of misalignment in the senses stresses your brain, your stomach muscles may start to shake, and nausea sets in. There are some motion sickness medications available with or without a prescription that can prevent this nausea. If this occurs unexpectedly, treatment may require that movement be stopped if necessary, or that the victim drink plenty of cold water.

Persistent nausea in the afternoon can also be a sign of more serious problems, such as ulcers, gallstones, or colitis. If a person experiences persistent nausea associated with other symptoms such as pain, it is generally recommended that they seek professional treatment. In the most severe cases, nausea can be a sign of long-term high blood pressure or a heart attack. Nausea with chest tightness, pain in the upper arms, or unexplained sweating can be life-threatening and warrant an immediate visit to a doctor.
