If you ate something that was bad or caught a stomach virus, you could be sick to your stomach and feel a little dizzy—especially if you have a high fever or got dehydrated. Anytime you are dizzy or feel like you may pass out, you need immediate medical care to be sure it is not something very serious. Some people may feel like this when they are having a panic attack, but don't ignore these symptoms if they are new and you have not discussed them with your doctor before.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Panic attacks are sudden feelings of terror that strike without warning. These episodes can occur at any time, even during sleep. A person experiencing a panic attack may believe that he or she is having a heart attack or that death is imminent. The fear and terror that a person experiences during a panic attack are not in proportion to the true situation and may be unrelated to what is happening around them. Most people with panic attacks experience several of the following symptoms: racing heartbeat, faintness, dizziness, numbness or tingling in the hands and fingers, chills, chest pains, difficulty breathing, and a feeling of loss or control. There are several treatments for panic attacks.
Anxiety is a feeling of apprehension and fear characterized by symptoms such as trouble concentrating, headaches, sleep problems, and irritability. Anxiety disorders are serious medical illnesses that affect approximately 19 million American adults. Treatment for anxiety may incorporate medications and psychotherapy.
Food poisoning is common, but can also be life threatening. The symptoms for food poisoning are fever, abdominal pain, headache, diarrhea, nausea and vomiting. Food poisoning has many causes, for example, chemicals (from toxic fish or plants) and bacteria (Staphylococcus aureus or Salmonella). Treatment of food poisoning depends upon the cause.
Heat exhaustion is a milder form of heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement fluids. Warning signs of heat exhaustion include heavy sweating, paleness, muscle cramps, tiredness, weakness, dizziness, headache, nausea or vomiting, and fainting. A person suffering from heat exhaustion should stop the activity are doing, move to a cooler environment, and rehydrate with liquids, for example, water or sports drinks. Complications of heat exhaustion are dehydration, muscle weakness, nausea, and vomiting. Heat exhaustion can progress to heat stroke (a medical emergency) if not treated.
