What are the signs before kidney disease?

Patient's question:

Got up every morning with lower back pain

Doctor's answer:

Analysis of the condition:
1. Edema often starts with the eyelids (in some patients, edema may first begin in the lower limbs), and severe cases can affect the entire body, even leading to pleural effusion and ascites.
2. Hypertension is one of the manifestations of kidney disease.
3. Frequent urination (increased frequency), urinary urgency (inability to hold urine), and dysuria (pain in the lower abdomen and urethra during urination).
Suggestions:
4. Most cases of lower back pain are dull pain, while surgical conditions may present with severe colicky pain.
5. Oliguria or anuria refers to less than 400 milliliters of urine per day (oliguria) or less than 100 milliliters per day (anuria).
6. Polyuria refers to more than 2500 milliliters of urine per day.
