What causes nausea?
Nausea is a sensation of stomach discomfort and desire for vomiting. Nausea may be a precursor to vomiting the contents of the stomach. There are many reasons for this situation and can often be stopped.
Nausea may occur for many reasons. Some people are highly sensitive to the speed or effects of certain foods, medicines, or certain medical conditions. All these things can cause nausea. The general reasons for nausea are described below.
Heartburn or gastroesophageal reflux disease (GERD)
Heartburn or gastroesophageal reflux disease (GERD) can cause the content of your stomach to cause back up of your oesophagal. It produces a burning sensation that causes nausea.

Take some medicines – for example, cancer treatments such as chemotherapy – can cause stomach upset or contribute to nausea. Be sure to read medication information carefully for whatever new medication you are taking. Talking about this information and talking about the treatments you talk to your doctor can help you reduce medication-related nausea.
Motion sickness and seaweed
Motion sickness and seaweed can be a result of a strange ride on a vehicle. This movement can not infect the brain in order to infect the brain, which can cause nausea, dizziness, or vomiting.
Eating or eating some foods like spicy or high-fat foods can cause stomach upset and nausea. Eating foods can make you allergic, which can cause nausea.
Acute pain can contribute to nausea symptoms. This is true for painful conditions like pancreatitis, gallbladder stones, and kidney stones.
Ulcers in the stomach, or the lining of the wound or small intestine, can contribute to nausea. When you eat, ulcers can cause a burning sensation and sudden nausea.

If your nausea is accompanied by symptoms of the heart attack then seek immediate medical attention. Symptoms of heart attack include chest pain, an acute headache, jaw pain, sweating, or pain in the left hand.
If you experience a severe headache, acute neck, difficulty breathing, or nausea associated with confusion, you should also take emergency care. If you suspect you have eaten poisonous substances or if you are dehydrated then seek medical help.
If your nausea has kept you unable to eat or drink for more than 12 hours, then see your doctor. You should also see your doctor if your nausea does not decrease within 24 hours of trying the over-the-counter intervention.

The treatment for nausea depends on the cause. Sitting in the next seat of a car, for example, speed can get rid of the disease. Motion sickness can also be helped with medicines, such as by scopolamine patches to get rid of dihydrates (Dramamine), antihistamine, or seaweed.
Taking medicines can also help to solve the underlying cause of nausea. Examples include pain relief agents for GERD or pain relief medication for an acute headache.
Keeping hydrated can help reduce dehydration after your nausea is reduced. It involves taking small, frequent snaps of clear liquids such as water, or drink with electrolyte.

Taking an anti-nausea drug (scopolamine) before a visit can also prevent motion sickness.
Changes in your eating habits, such as small, frequent eating foods, can help reduce the symptoms of nausea. Nausea can be reduced by avoiding acute physical activity after meals. It may also help to avoid spicy, high fat, or greasy food. Examples of foods that are less likely to cause nausea to include cereals, crackers, toast, gelatine and broth.
