Nausea
Persistent nausea is a non-specific signal — common causes range from gastritis to medication side effects to early diabetes to kidney or liver disease. The lab work-up is broad-net.
What it means
Nausea is the conscious experience of needing to vomit. Acute nausea is usually viral, food-related or medication side effect. Chronic or recurrent nausea is broader — gastritis, gallbladder disease, peptic ulcer, pregnancy, migraine, anxiety, uremia, hyperglycaemia, hypercalcaemia, hyponatraemia, hyperthyroidism, adrenal insufficiency, increased intracranial pressure. The lab approach casts a wide net while clinical history narrows the most likely category.
Common causes
- Gastritis, peptic ulcer, GERD — often related to meals.
- Gallbladder disease — after fatty meals.
- Pregnancy — first-trimester morning sickness; always test in women of reproductive age.
- Medications — opioids, antibiotics, chemotherapy, metformin.
- Diabetic ketoacidosis or hyperglycaemia — undiagnosed or poorly controlled diabetes.
- Kidney failure (uraemia) — late-stage chronic kidney disease.
- Liver disease (hepatitis, fatty liver) — particularly with abdominal discomfort.
- Hypothyroidism, hyperthyroidism, adrenal insufficiency — endocrine.
- Migraine, increased intracranial pressure — neurological.
Lab work-up approach
Mediora interprets: glucose + HbA1c (diabetes), creatinine + eGFR (kidney), ALT + AST + bilirubin (liver), TSH (thyroid), sodium + potassium + calcium (electrolytes). Pregnancy test is essential in women of reproductive age — not via Mediora.

When to see a doctor
Persistent nausea longer than a week, with weight loss, vomiting blood, severe abdominal pain, signs of dehydration, or in a pregnant woman who can't keep fluids down — warrants a primary-care visit. Severe acute nausea with confusion or chest pain is an emergency.
