Nausea is stomach discomfort and the sensation of feeling to vomit. Nausea is an uneasy feeling of the vomiting that often comes before vomiting. The condition has many causes and can often be prevented.
What causes nausea?
Nausea can occur because of variety of causes. Some people are highly sensitive to motion or to certain foods, medications, or the effects of certain medical conditions. All these things can result in nausea. Common causes of nausea are given below.
Heartburn or gastroesophageal reflux disease (GERD)
Heartburn or gastroesophageal reflux disease (GERD) can cause your stomach’s contents to move back up(regurgitate) your esophagus when you take food. This creates a burning sensation that causes nausea.(1)
Infection or virus
Bacteria or viruses can affect the stomach and cause nausea. Foodborne bacteria can lead to a condition called as food poisoning. Viral infections can also cause nausea.
Taking certain medications — for example, cancer treatments such as chemotherapy — can upset the stomach and lead to nausea. Make sure to correctly read the medication information for any new treatments you may be following.
Reading this information and taking suggestions of your doctor about any medications and treatments you’re taking can help you reduce medication-associated nausea.
Motion sickness and seasickness
Motion sickness and seasickness can result from a rough ride on a vehicle. This movement can lead to the messages transmitted to the brain to not syncronize up with the senses, resulting in nausea, dizziness, or vomiting.
Overeating or eating certain foods, such as spicy or high-fat content foods, disturb the stomach and lead to nausea. Eating foods which are allergic to you can also result in nausea.
Ulcers, or sores in the stomach or the lining of the small intestine, can lead to nausea. When you eat food, an ulcer can cause a burning sensation and sudden nausea.
Nausea is also a symptom of several other medical conditions, including:
- benign paroxysmal positional vertigo (BPPV)
- ear infection
- heart attack
- intestinal blockage
- liver failure or liver cancer
When to seek medical help
Go for immediate medical help if your nausea is occured with the symptoms of heart attack. Heart attack symptoms include crushing chest pain, abnormal heart beat, anxiety an severe headache, jaw pain, sweating, or pain in your left arm.
You should also go for urgent medical help if you feel nausea combined with a intense headache, stiff neck, trouble breathing, or confusion. Seek medical attention if you suspect that you’ve ingested a poisonous substance or if you’re dehydrated.
See your physician if you didn’t eat or drink for more than 12 hours because of nausea. You should also see your physician if your nausea doesn’t goes down within 24 hours of trying over-the-counter measures.
Always go for medical attention if you’re concerned you may be having medical emergency.
How is nausea treated?
Treatment for nausea depends on the cause.
Sitting in the front seat of a car may help in motion sickness. Motion sickness can also be treated with medications such as dimenhydrinate (Dramamine), an antihistamine, or by applying a scopolamine patch to relieve seasickness.
Taking medications to mark nausea’s basic cause can be also helpful. Examples include stomach-acid reducers for GERD or pain-relieving medications for severe headaches.
Keeping yourself hydrated can help to lower dehydration after your nausea eases up. This includes taking adequate drinks more such as water or an electrolyte-containing drinks.
When you start re-uptake of food, it’s helpful to follow the BRAT diet (bananas, rice, apple sauce, and toast) until your stomach is more settled.
How is nausea prevented?
Avoiding nausea triggers can help to prevent nausea’s arrival. Following should be avoided:
- twinkling or shivering lights, which can trigger migraine attacks
- heat and humidity
- sea trips
- strong odors, such as perfume and cooking smells
Taking an anti-nausea medication such as scopolamine before a vehicle ride can also prevent motion sickness.
Changing your eating habits, such as eating small, frequent meals, can help to lower nausea symptoms. Avoiding hard physical activity after eating can also minimize the chances of nausea. Avoiding spicy, high-fat, or greasy foods can also help and prevent nausea.
