Would having sinusitis explain why i'm so tired all the time?

No: Chronic sinusitis is defined as signs and symptoms of sinus inflammaton persisting beyond 8-12 weeks. Certainly we can feel run down with any chronic illness but i would encourage you pursue a thorough medical evaluation by your primary care provider to exclude more common causes of tiredness.

Maybe: If the sinusitis leads to nasal obstruction this can lead to poorer sleeping and fatigue. You should contact an ENT doctor for a full history and exam.

Fatigue: Hello. Sinusitis can play a role in our overall health by decreasing our sleep or having a negative effect on our sleep quality. The immune system gets chronically stressed if your sinus disease is persistent. These in turn commonly lead to fatigue.
