Physical examination: The doctor will perform a physical exam to check for signs of infection or other medical conditions.

Diagnostic tests

The doctor may order the following tests to identify the underlying cause of your NS.

Imaging tests: These include imaging of the chest and abdomen to look for any abnormalities or tumours that could be causing the NS.

These supplements can also help with hormonal imbalances that may be causing this condition.
