How does extreme fatigue affect a diver suffering from Type II DCS?

Extreme fatigue can significantly worsen the symptoms of a diver suffering from Type II Decompression Sickness (DCS). When a diver is fatigued, their body is less capable of coping with the physiological stress caused by DCS, which can lead to increased severity of symptoms such as pain, neurological disturbances, and overall physical impairment.

Fatigue can compromise a diver's ability to make sound judgments, react quickly, and perform necessary tasks for managing DCS effectively. Additionally, a fatigued state may hinder blood circulation and decrease the overall efficiency of oxygen transfer within the body, exacerbating the issues associated with DCS. This can lead to a more rapid progression of symptoms and may complicate treatment outcomes.

Understanding the interplay between fatigue and DCS is vital for divers, as it emphasizes the importance of maintaining physical and mental fitness before and after dives to help mitigate the risks associated with these conditions.
