Nausea is feeling an urge to vomit. It is often called “being sick to your stomach.”
Vomiting or throwing-up is forcing the contents of the stomach up through the oesophagus and out of the mouth.
Many common problems may cause nausea and vomiting, including:
- Food allergies
- Infections of the stomach or bowels, such as the “stomach flu” or food poisoning
- Leaking of stomach contents (food or liquid) upwards (also called gastroesophageal reflux or GERD)
- Medicines or medical treatments, such as cancer chemotherapy or radiation treatment
- Migraine headaches
- Morning sickness during pregnancy
- Seasickness or motion sickness
- Severe pain, such as with kidney stones
Nausea and vomiting may also be early warning signs of more serious medical problems, such as:
- Blockage in the intestines
- Cancer or a tumour
- Ingesting a drug or poison, especially by children
- Ulcers in the lining of the stomach or small intestine
Medical Marijuana Efficiency
The anti-nausea effects of medicinal marijuana are well known scientifically and by those who self-proscribe cannabis to relieve nausea and vomiting. While cannabinoids isolated from the cannabis plant are known to also help to mitigate nausea, smoking medical marijuana provides superior treatment for vomiting when compared to THC ingested orally.
