Upset stomach and dizziness can be attributed to several different causes. A person may experience an upset stomach as a direct result of taking certain medications, or may experience stomach upset after consuming alcohol or taking recreational drugs. Allergic reactions or food intolerance can also cause stomach upset along with dizziness. However, when fever and upset stomach are present at the same time, this is usually due to an underlying illness. These symptoms may also be accompanied by diarrhoea, which is also usually due to an underlying disease.
Some people have a bad reaction to certain medications, such as antibiotics. During the course of such a reaction, gastrointestinal discomfort may occur. In general, upset stomach and dizziness are not present at the same time due to this problem, but it is possible. The upset stomach experienced is usually due to antibiotics that destroy bacteria necessary for proper digestion. Some medication directions require a person to take them on an empty stomach, which can also cause discomfort. In general, side effects are minimized or go away completely once a person is allowed to eat.
When alcohol is consumed on an empty stomach, a person is likely to experience an upset stomach and dizziness as a result. This is because food slows down the rate at which alcohol is absorbed, and without food, alcohol can affect the body much faster. Carbonated alcoholic beverages are also known to irritate the delicate lining of the stomach, which can cause discomfort. The dizziness you feel is a direct result of alcohol on the brain. Similar symptoms are associated with recreational drug use.
Certain food choices can also cause stomach upset. For example, although garlic is often used to flavor food recipes and is even used as a home remedy for certain symptoms, it is also toxic to some people. People with an adverse reaction to garlic may experience stomach upset and dizziness. While such a reaction is rare, it is more commonly reported by people taking garlic supplements.
When these symptoms are accompanied by fever or diarrhoea, this is commonly due to an illness, such as a viral or bacterial infection. If this is the case, other symptoms experienced may include headache, fever, chills, and muscle aches. Health experts recommend that people experiencing an upset stomach and dizziness, along with other unusual symptoms, seek medical attention if the cause is not immediately known.
