Sore Throat in Adults

Common Causes

• Viral infections — Colds, flu, or mono might lead to sore throats in adults due to common exposure in workplaces or social settings.
• Strep throat — Bacterial infection from group A strep could cause sore throats, especially in crowded environments.
• GERD (acid reflux) — Stomach acid backing up into the throat may irritate it, common in adults with poor diet or stress.
• Allergies or irritants — Postnasal drip from pollen or smoke exposure might dry out and inflame the throat.
• Muscle strain — Yelling or talking loudly for long periods could strain throat muscles.
