The stimulating effects of caffeine are evident throughout your body. It can induce an elevated heartbeat and increase your mental focus and alertness. You might also experience an increased body temperature, and some people develop an overactive bladder stimulated by the caffeine. But caffeine isn't the only factor that can affect how frequently you urinate.
Frequent Urination Causes
Some causes of an overactive bladder are more common than others. The condition often develops in people who are diabetic or pregnant, as well as in men with prostate problems. According to MedlinePlus, other causes can include anxiety, tumors, medications, an enlarged prostate and nervous system diseases.
Effects of Caffeine
Caffeine's effects tend to be more drastic when larger amounts of the stimulant are consumed. But this isn't true across the board -- some people are more sensitive to caffeine and can develop side effects like an overactive bladder much faster than others. Anything under 500 or 600 milligrams of caffeine consumed in a day is considered moderate and safe, but if you want to avoid the effects of an overactive bladder, you might need to cut yourself off before reaching this threshold.
Complications
Complications of an overactive bladder are rare, but they do occur. Complications can include fever, vomiting, chills, pain in your back or sides, fatigue, weight loss, or bloody or cloudy urine, according to MedlinePlus. If you develop these complications, call or visit a doctor immediately.
Considerations
Don't assume you know the exact cause of your frequent urination. Multiple factors may be affecting your bladder's activity. If you urinate frequently at night, avoid caffeinated drinks in the evening and don't consume large amounts of fluids before going to bed. Alcohol consumption can also affect your bladder's activity.
