My mom got dehydration (no fever, headache or breathing problem) on 3rd April, then on 7th she got loose motion and vomiting (no vomiting before and after this date but vomiting sensation was there). She was treated accordingly. But for 10 days, her weakness continued, so blood analysis was suggested. There kft showed drastic abnormality. Blood urea:122 & creatinine 6.23.
