Incontinence: Your symptoms are consistent with possible stress incontinence (sui) which occurs with activities such as coughing/sneezing, lifting, straining, exercising, and change in position, and is related to weakened pelvic floor muscles. Another possibility is non-urge, non-stress incontinence which is sudden uncontrolled urine loss due to involuntary bladder contraction. Urological evaluation recommended.
