Urinary Incontinence: This is involuntary release of urine. Being overweight can contribute to urinary incontinence. A heavy abdomen due to body fat deposit may cause valve of urinary bladder to be weakened. The weight also exerts pressure on the urinary bladder, trying to push urine out. This results to leakage of urine when coughing, sneezing or laughing. This is because of a slight relaxation of the bladder valve that normally will not result to leakage. It can even result to bed wetting at night. This particular problem can be a very effective motivator to lose weight.
