Top 10 Yellow / Green Vomit Causes

  1. 1.Viral (Norovirus) Infection

    Noroviruses are a group of related viruses that leads to nausea, vomiting, diarrhea, and cramps. These viruses cause gastroenteritis, an inflammation of the stomach and intestines. When the diarrhea and/or vomiting is severe, dehydration can occur. Symptoms of dehydration include a dry mouth, dizziness, urinating less frequently and dark urine.

    You can safely treat this condition at home. Make sure you drink plenty of water and fluids (Gatorade, Pediatlyte) to replace what is lost with diarrhea. If symptoms of dehydration occur or you are unable to keep down any liquids, seek care at your primary care physician or an urgent care.

  2. 2.Viral (Rotavirus) Infection

    Rotavirus is a virus that causes an infection of the gut, known as gastroenteritis. Symptoms include diarrhea, vomiting and fever. When the diarrhea and/or vomiting is severe, dehydration can occur. Symptoms of dehydration include a dry mouth, dizziness, urinating less frequently and dark urine.

    You can safely treat this condition at home. Make sure you drink plenty of water and fluids to replace what is lost with diarrhea. Eat as normally as possible.

  3. 3.Small Bowel Obstruction

    A small bowel obstruction is most often caused by adhesions after surgery, which make it difficult or impossible for food and fluid to pass through the bowel. This causes a blockage. Small bowel obstructions often cause nausea, vomiting, abdominal pain, and constipation.

    This condition requires hospitalization. Treatment depends on the severity of the obstruction but surgery is likely.

    Rarity:

  4. 4.Gall Bladder Infection (Cholecystitis)

    Cholecystitis is the inflammation of the gallbladder. The gallbladder holds bile (a digestive juice). Gallstones can form when the bile gets thick, and these stones can block up the gallbladder and cause inflammation.

    You should seek immediate medical care at an ER, where an ultrasound of your abdomen and blood tests would confirm a diagnosis. Not seeking care may lead to the gallbladder bursting and causing a deadly infection in the abdomen.

    Rarity:
    Uncommon
    Top Symptoms:
    abdominal pain (stomach ache), nausea, loss of appetite, diarrhea, constipation
    Symptoms that always occur with gall bladder infection (cholecystitis):

    pain in the upper left abdomen, pain in the lower left abdomen
    Urgency:
    Hospital emergency room
  5. 5.Ovarian Torsion

    The twisting, or torsion, of the ovary around its surroundings. This may result in loss of blood to both the ovary and the fallopian tube. When diagnosed, this condition is considered an emergency and requires immediate surgery.

    You should go to the emergency room immediately. Diagnosis is made by ultrasound and surgery is required if the diagnosis is confirmed.

    Rarity:
    Rare
    Top Symptoms:
    abdominal pain (stomach ache), nausea or vomiting, nausea, moderate abdominal pain, abdominal cramps (stomach cramps)

  6. 6.Influenza

    Influenza, or Flu, is an infection of the airway caused by the flu virus, which passes through the air and enters the body through the nose or mouth. The symptoms are similar to those of a cold, but the flu is usually more serious.

    If your flu-like symptoms are existing for less than 48 hours, it might be helpful to seek care by telephone or in a walk-in-clinic to get a course of oseltamivir (Tamiflu). Most people will get better on their own by drinking lots of fluids and taking an over-the-counter medication such as acetominophen (Tylenol) to help with aches or fever.

    Rarity:
    Common
    Top Symptoms:
    fatigue, headache, loss of appetite, cough, muscle aches

    Indigestion, also known as dyspepsia, is a condition that causes pain or discomfort in the stomach after eating. In some cases, indigestion also causes heartburn, burping, and nausea. Indigestion or dyspepsia is a very common complaint. Every year, about 1 in every 4 people will experience an episode of dyspepsia, of which most cases do not have a serious underlying cause.

    You can treat this at home with antacids. Many people find simple dietary changes to be beneficial such as avoiding spicy or fatty foods and drinking less tea or coffee.

    Gallstones are hardened deposits of digestive fluid that can form in your gallbladder. Your gallbladder is a small, pear-shaped organ on the right side of your abdomen, just beneath your liver.

    You should visit your primary care physician to speak about your pain. Your doctor would perform an ultrasound to recognize something going on in your gallbladder.
