This is not unusual
Do the following
1. Drink fluids as normal
2. Check your weight daily to check for unexpected weight gain
3. If weight gain and not passing enough urine, will need further tests
a) Blood tests- CBP, KFT, HbA1C, LFT, ESR, Calcium and Phosphate
b) Urine microscopy
c) Ultrasound abdomen
All the best.

Low urine output during gastritis is commonly due to dehydration, especially if you have acidity, poor oral intake, nausea, or vomiting. Even if you are drinking 3 liters of water, poor absorption and ongoing gastric irritation can still cause reduced urine output.
Possible causes include:
Dehydration during gastritis
Reduced oral intake of salts
Temporary kidney stress
Urinary tract issue (less common)
Next Steps
Continue adequate fluids, including ORS / electrolyte solutions
Take gastritis treatment regularly (PPI before breakfast)
Avoid spicy, oily, alcohol, tea, coffee, and smoking
Monitor urine color (dark yellow suggests dehydration)
Investigations advised:
RFT (kidney function test)
Urine routine examination
Ultrasound abdomen (KUB)
Health Tips
If problem persists
If urine output remains low, or you develop swelling of legs/face, severe abdominal pain, or vomiting — consult a doctor urgently.

Low urine output (only urinating every 5–6 hours) despite drinking 3 liters of water per day is not normal and needs attention, especially when you already have gastritis.
Possible reasons include:
• Dehydration from ongoing gastritis (vomiting, reduced appetite, or poor fluid absorption)
• Some people with gastritis take antacids or PPIs that can indirectly affect fluid balance
• Early/mild kidney function issue (prerenal azotemia) from low effective fluid volume
• Prostate enlargement or bladder outlet problem (more common in men)
• Medications (if you take any diuretics, painkillers, or blood pressure tablets)
• Rarely something more serious like obstruction or acute kidney injury
Since you are drinking a good amount (3 L/day), the body should produce ~1.5–2.5 L urine per day (roughly every 2–4 hours during the day). Producing urine only every 5–6 hours means your kidneys are either not getting enough effective blood flow or there is a partial block somewhere — this should be checked.
Next Steps
1. See a doctor soon (within 1–3 days if no other alarming symptoms, or today/tomorrow if you have any of the red flags below):
• General physician or nephrologist (kidney doctor) is best.
• Bring: list of medicines (especially for gastritis), how much urine you pass each time (estimate in ml if possible), any swelling in legs/face, weight change.
2. Tests they may do:
• Urine routine + specific gravity
• Blood tests: creatinine, urea, electrolytes
• Ultrasound abdomen & pelvis (to check kidneys, bladder, prostate if male)
3. Go to ER / urgent care immediately if you also have:
• Very little or no urine for >8–12 hours
• Swelling in legs, face, or hands
• Severe weakness, confusion, nausea/vomiting
• Pain in lower back or abdomen
• Fever
Health Tips
• Keep drinking 3 L water (or more if you can) — spread it evenly during the day (do not drink 1 liter at once).
• Add a pinch of salt + lemon or ORS (oral rehydration solution) once or twice a day — helps absorption when gastritis is present.
• Avoid caffeine, alcohol, and very sweet drinks — they can increase fluid loss.
• Track exactly: Write down time + approximate amount every time you urinate for 1–2 days (helps doctor see the pattern).
• While waiting for doctor: Avoid NSAIDs (ibuprofen, diclofenac) — they can worsen gastritis and kidney function.
Use only doctor-approved gastritis medicine.
This is usually fixable once the cause is found (most often simple dehydration or gastritis-related), but don’t ignore it for weeks.

Take care and get checked soon!

Advise after blood urea, serum creatinine
Tab nexpro RD40 ONE IN EMPTY STOMACH FOR ten days.
Mucain gel 10ml without water nothing by mouth till 30min can be taken 3to4 times for gastritis.
Citralka syr 15 ml with half glass of water three times after food. It increase Urine output. So intake must be proper.

Consult a doctor with kidney function test report.

This can happen with gastritis. Even if you’re drinking 3 litres, during acidity the body doesn’t absorb fluids properly and urine output can drop. It’s usually temporary and improves once the stomach settles. If there’s no burning while urinating, fever, or swelling, it’s less likely to be a kidney problem.
Next Steps
• Don’t push plain water alone — add ORS / electrolytes through the day
• Take your gastritis medicines regularly (especially PPI before breakfast)
• Eat small, light meals; avoid spicy, oily, caffeine for now
• If urine stays low beyond 24–48 hrs or you feel dizziness/swelling, get urine routine + creatinine checked
Health Tips
I know this feels worrying, but in most cases it settles once gastritis is controlled. If you want, we can quickly go over your symptoms, meds you’re taking, and reports together to be sure nothing is being missed and help you recover faster.
