Prescription nausea medication online: 15-minute Rx available

Several factors can contribute to nausea and vomiting. While some people are sensitive to specific foods, others may experience nausea due to health conditions. Some common causes of nausea and vomiting include:

• Gastroesophageal reflux disease (GERD): GERD causes the stomach's contents to flow back into the esophagus. When the stomach contents move back up the gastrointestinal tract, you may experience a burning sensation (heartburn), which can coincide with nausea and vomiting.

• Bacterial or viral infections: Both viral and bacterial infections can cause stomach pain and discomfort, including nausea. For example, food-borne bacteria and toxins can cause food poisoning, while viruses can cause viral gastroenteritis (intestinal or “stomach” flu).

• Certain medications: Nausea is a common side effect of many medications. If you start a new treatment, such as chemotherapy, you might notice new symptoms of nausea.

• Motion sickness: Motion sickness happens when your brain can't process the information from your eyes, ears, and body. When your brain's signals don't match up with your senses, you might experience nausea and vomiting.

• Food sensitivities: Eating certain foods, such as spicy foods or dairy, can cause stomach discomfort. Food allergies and sensitivities can also contribute to nausea symptoms.

• Pain: Pain can exacerbate nausea symptoms. If you have pancreatitis, gallbladder stones, kidney stones, or migraine headaches, you might experience severe nausea.

• Stomach ulcers: Ulcers (sores in the stomach or intestinal lining) can cause nausea. When you eat, ulcers trigger an inflammatory response. You might feel especially nauseous in the morning or after going a few hours without food.

• Pregnancy: Hormonal changes--especially in early pregnancy--can cause nausea and vomiting. Sometimes nausea can be very severe or can be a symptom of hyperemesis gravidarum, a prolonged nausea and vomiting disorder that can cause pregnancy complications.

Nausea is characterized by stomach uneasiness and discomfort. Nausea often coincides with the urge to vomit but doesn't always lead to vomiting. If you're feeling nauseous, you might also experience:

• Headache

• Dizziness

• Abdominal pain or tenderness

• Low fever

• Chest discomfort

• Heartburn

• Diarrhea or constipation

• Gas

• Sweats or flushing

• Vomiting

Vomiting is caused by forceful emptying of the stomach contents through the esophagus and mouth ("throwing up"). This can often occur quickly and unexpectedly. Triggers that cause vomiting can come from several parts of the body, including:

• The stomach and intestines (infection, food irritation, or injury)

• The inner ear (dizziness and motion sickness)

• The brain (head trauma, tumors, migraines, or infection)

If you have chronic nausea, you may experience other uncomfortable symptoms, including:

• Constantly feeling like you're sick or about to vomit

• Excess salivation

• Lack of appetite

• Uncontrollable sweating

• Repeated stomach muscle contractions that you cannot control (retching)

• Stomachache or upset stomach

• An uneasy feeling in the chest, upper abdomen, or back of the throat

• Difficulty keeping food down

Several temporary medical conditions can contribute to nausea, including:

• Heartburn or gastroesophageal reflux disease (GERD)

• A bacterial infection or virus

• Motion sickness or seasickness

• Food sensitivities or allergies

• High levels of stress and anxiety

• Food poisoning

• Migraine headaches

• Hormonal changes (for example, morning sickness due to pregnancy)

In addition, some chronic medical conditions can cause nausea including:

• Gallbladder or kidney stones

• An intestinal obstruction

• A stomach ulcer

• Meningitis

• Pancreatitis

• Mental health conditions, such as depression or an anxiety disorder

If your nausea symptoms persist for more than 24-48 hours after taking over-the-counter medicine, talk to your healthcare provider. In most cases, nausea goes away without treatment and isn't a medical emergency. However, if your symptoms don't go away, medical care may be necessary.

Seek immediate medical help if your nausea coincides with:

• Dehydration

• A stiff neck

• Confusion

• Blood in your vomit or stool

• Difficulty waking up

• Severe pain in your lower right abdomen

Many patients are sensitive to certain foods and may benefit from simple dietary changes. For example, you might:

• Eat smaller meals to avoid over-distending the stomach.

• Try eating a bland diet with easy-to-digest foods, such as bananas, rice, apples, and toast (the “BRAT diet”).

• Avoid food sensitivities and allergens, such as dairy, gluten, spicy foods, or high-fat foods.

• Eliminate or decrease common nausea triggers, such as alcohol and caffeine.
