Throat infections are among the most common ailments, affecting people of all ages. In this video, Dr Nagendra from Maruti Clinic provides a comprehensive overview—explaining causes, symptoms, and how to treat them effectively.
What Causes Throat Infections?
Dr Nagendra outlines several triggers responsible for throat infections:

- Bacterial infections, most notably Streptococcus pyogenes (strep throat)
- Allergens and irritants, including dust, pollutants, or smoking

- Hoarseness or loss of voice may occur in some cases
Diagnosing Your Condition
A physical consultation usually includes:
- Detailed symptom review – onset, duration, severity
- Throat examination – checking for redness, spots, swelling

Treatment varies based on cause:
- For viral infections:
- Home care—rest, hydration, and warm drinks
