Kidney Self-Repair Ability
Kidneys can repair themselves to some extent after minor injuries. This includes recovering from mild dehydration or minor infections.
Limits of Repair
Severe damage, such as from chronic diseases or significant injury, may not be reversible. Scarring and loss of function can occur.
Factors Affecting Healing
a. Overall health
b. Underlying conditions (e.g., diabetes, hypertension)
c. Timeliness of medical intervention
When Medical Intervention is Necessary
Seek medical care if experiencing symptoms like persistent pain, swelling, or changes in urination. Early intervention can prevent further damage.
Importance of Medical Care
Regular check-ups and managing chronic conditions are crucial for maintaining kidney health and preventing irreversible damage.

So my dad just got test results back, and his creatinine levels are at 7.2. I'm really worried about what this could mean for his health. Can you explain the potential issues high creatinine levels can cause? Also, what steps can we take to try and lower these levels? Any advice would be really helpful.

I'm really concerned about my dad. He was suspected to have multiple myeloma, but his PET scan came back normal. Now he's losing a lot of protein through urine. His latest report shows 1260mg protein in 1750ml of urine over 24 hours. What could this mean, and what should we do next? We live in Thane West, 400607.

Given the high level of protein in your father's urine, its important to investigate the underlying cause further. A visit to a nephrologist and additional tests to assess kidney function and look for signs of kidney damage or systemic diseases will be crucial. I would also recommend that you closely monitor his condition and follow up with your healthcare provider for further guidance.

Can a urine dysmorphic RBC test really tell if the blood in my urine is coming from my kidneys or the urethra? I had results showing 1012 cellshpf in my urine, but when I did the test again 4 days later, it dropped to 12 cellshpf. Does this mean it was a false reading, or could the sample have been off? I'm a bit confused about what to make of these results.

Yes ideally Dysmorphic RBCs indicate renal problem,but in your case as it is an incidental finding for once and is not continuing you can ignore it,if you are woried visit Nephrologist for evaluation and appropriate management
