Age 66 , long hesitation when peeing, just gained some weight. Is it weight, age or something else?

At 66, new urinary hesitancy is most likely from an enlarged prostate, not just age or weight.

The evidence points to benign prostatic hyperplasia (BPH) as the primary suspect. In a study of 2,741 men with lower urinary tract symptoms due to BPH, the average age was 64.3 years, and hesitancy was a statistically significant symptom linked to the condition [1]. Another study of 104 men with acute urinary retention found that 73% had attributed their urinary symptoms to aging and delayed seeking care for over a year [2]. This pattern suggests that dismissing hesitancy as "just age" is common but dangerous.

Weight gain can worsen the problem but is rarely the root cause. Excess body fat, especially around the abdomen, increases pressure on the bladder and can compound the obstruction from an enlarged prostate. The same study of 2,741 men found that hypertension and diabetes, both linked to weight, were independently associated with chronic kidney disease in men with BPH [1]. So weight is a contributing factor, not the primary driver.

The real risk is letting this go unexamined. Hesitancy is a classic symptom of BPH, but it can also signal prostate cancer, a urinary tract infection, or a neurological issue. A simple digital rectal exam, a PSA blood test, and a urine flow study can sort this out. The evidence does not support blaming age or weight alone. See a doctor and get the prostate checked.

My call: this needs a medical workup, not a lifestyle guess. Confidence: high.
