What happens when you lose your pectoral muscle?

Losing your pectoral muscle, whether due to injury, surgery, or muscle wasting, can lead to significant physical changes, including a decrease in upper body strength and stability. This loss may affect your ability to perform everyday activities that involve pushing or lifting. Additionally, it can lead to an imbalance in muscle development, potentially causing postural issues or discomfort. Rehabilitation and targeted exercises may help mitigate these effects, though full recovery can vary based on the severity of the loss.
