Frequent vomiting: causes and when to seek help

Frequent vomiting needs attention because fluid loss can become serious and the underlying cause may require treatment. Causes include Gastroenteritis, Food Poisoning, migraine, medication effects, and abdominal conditions such as Gallstones or Pancreatitis. The timing, vomit appearance, pain, fever, diarrhoea, headache, and ability to keep fluids down help determine urgency.

Infection or contaminated food often brings nausea, vomiting, cramps, diarrhoea, or fever. Migraine may cause vomiting with a significant headache and sensitivity to light. Severe upper-abdominal pain that travels to the back needs urgent assessment because Pancreatitis is one possible cause. Gallstones may cause intense pain under the ribs with nausea.

Vomiting with a severe headache, stiff neck, rash, confusion, or unusual sleepiness can occur with serious illness such as Meningitis. In babies and young children, Rotavirus Infection can rapidly reduce fluid intake and wet nappies.

Take small, frequent sips of water or an oral rehydration drink. If vomiting settles, try plain foods in small portions and avoid alcohol and heavy meals until recovery. Rest, wash hands carefully, and avoid preparing food for others while infectious illness is possible. Do not start anti-vomiting medicines or antibiotics without medical advice, particularly for children, pregnancy, or chronic illness.

Get urgent medical help for blood or coffee-ground material in vomit, green vomit, severe or worsening abdominal pain, a swollen abdomen, fainting, confusion, stiff neck, or a severe headache. Seek prompt care if you cannot keep fluids down, urinate much less, have a very dry mouth, or become unusually weak. Children, older adults, and pregnant people may need earlier assessment.

What cause best fits the timing and other symptoms? Do I need hydration treatment, urine or blood tests, or abdominal assessment? Which foods, medicines, and warning signs should I watch during recovery?
