Unintentional Weight Loss
This condition is also called unplanned weight loss. [8] It is usually present in the late stages of bladder cancer. If you lose weight following a stressful event or after following a diet or exercise plan, it is usually not a problem.
Unplanned weight loss happens even when you have not gone through any of these things. The weight loss is generally unexpected. If you experience significant or progressive weight loss without doing anything to trigger it, it may be a sign of a problem.
Many health conditions can cause unexpected weight loss. While bladder cancer is one of them, it is not the only potential cause. You should see a doctor for a proper diagnosis.
