Nausea and vomiting are not considered to be illnesses, butthe symptoms that suggest that’s something is wrong in our body. When throwing up,stomach is turning inside out, overcoming the pressure to keep the food inside.
Nausea and vomiting may occur because of the followingreasons: acute gastritis, signals from the brain, some other stomachillnesses, some medical treatments and because of the mechanical obstruction ofthe bowels.
Acute gastritis is actually stomach inflammation, caused by infections,stomach flu, food poisoning, or some substances that irritate stomach. Infectionscould be viral, bacterial or parasite origin, usually followed with abdominalpain or diarrhea. Bacterial toxins are responsible for food poisoning andsymptoms could easily last for a couple of days. Most likely, food poisoning areto be contracted from Salmonella, Campylobacter, Shigella, E. coli,Listeria, or Clostridium botulinum (botulism) infection.
Alcohol, smoking and some anti-inflammatory medications(aspirin or ibuprofen) irritate the stomach and may provoke nauseas andvomiting. Peptic ulcer and Gastroesophageal reflux disease (GERD) are otherpossible explanations for nausea and vomiting cases.
Many medications side effects includes nausea and vomiting. Theworst are anti-cancer drugs, especially chemotherapy medications and radiationtherapy. Narcotic pain drugs and other anti-inflammatory (steroids andnon-steroid) medications and antibiotics also have the same side effects.
Bowel obstruction is usually connected with abdominal pain,inability to pass gas, decrease in bowel movements and nausea and vomiting. Smallintestine gets blocked, the content of the intestines cannot pass through andthere’s a buildup of food and fluids in the stomach.
The first trimester of pregnancy and sometimes even thewhole pregnancy is often associated with the nausea and vomiting. Possible explanationmight be the changes in the blood levels of hormones, that normally follow pregnancy.
When it comes to children sometimes you can’t tell if thechild is vomiting or spitting up. If it happens after feeding and only a smallamount comes up, it could be just spitting.
When a newborn is vomiting strongly after eating (the vomitis flying across the room) it is possible that a child is suffering frompyloric stenosis. This is narrowing of the area at which the stomach emptiesinto the small intestine. The diagnose is confirmed with an ultrasound andsurgically treated.
Sometimes, babies have vomiting associated with pain, cry uncontrollably andthe stool contains blood in it. A child have to be taken to the doctor, who mightdiagnose intussusception (one segment of the bowel is pushing into an neighboringsegment).
Vomiting and nausea associated with diarrhea could mean thata child is having a viral infection, or the baby formula you have been using tofeed him/her is not appropriate.
Any vomiting in children that lasts for more than 24 hoursis the reason the consult the doctor about the situation.
