You urinate a lot but is not pregnant?

Excessive urination, medically known as polyuria, can be caused by several factors. Some of the possible causes for urinating a lot but not being pregnant include:

1. Diabetes Insipidus: A condition caused by the body's inability to properly conserve water. This results in frequent and excessive urination.

2. Diabetes Mellitus (Uncontrolled): High blood sugar levels can cause the kidneys to filter more glucose, leading to increased urine production.

3. Overhydration: Consuming excessive fluids, especially water, can result in increased urine output.

4. Medications: Certain medications, such as diuretics (used to increase urine production), can cause frequent urination.

5. Urinary Tract Infection: A bacterial infection in the urinary tract can lead to frequent urination and other symptoms.

6. Caffeine or Alcohol Consumption: Consuming caffeine or alcohol can stimulate the kidneys and cause temporary increases in urine production.

7. Kidney Disease: Conditions that affect kidney function can lead to excessive urine production, such as chronic kidney disease or kidney failure.

8. Prostatitis (in Men: Inflammation of the prostate gland can cause frequent urination, especially at night.

9. Overactive Bladder: A condition characterized by sudden, strong, and frequent urges to urinate.
