Strep throat is a common bacterial infection caused by Streptococcus pyogenes bacteria, primarily affecting the throat and tonsils. While a sore throat is its hallmark symptom, the fatigue experienced can be profound, impacting daily activities. This weariness stems from the body’s intense effort to fight the infection.
Why Strep Throat Causes Tiredness
Tiredness during a strep throat infection stems from the body’s robust immune response as it combats the Streptococcus pyogenes bacteria. When the immune system detects the infection, it mobilizes various cells and proteins to neutralize the threat. This activation requires significant energy, diverting resources from normal bodily functions and decreasing overall energy levels.
The immune response also triggers inflammation, a natural process designed to isolate and eliminate the infection. During inflammation, the body releases signaling molecules that contribute to systemic symptoms like fatigue and a general feeling of malaise. The body’s intense effort to heal and the widespread inflammatory reaction combine to produce the noticeable tiredness associated with strep throat.
Other Common Strep Throat Symptoms
While fatigue is a prominent symptom, strep throat typically presents with a range of other indicators. A sudden and severe sore throat is characteristic, often accompanied by pain when swallowing. Many individuals experience a fever, which can begin suddenly. The tonsils may appear red and swollen, sometimes displaying white patches or streaks of pus.
Other common signs include swollen, tender lymph nodes in the neck. Some individuals, particularly children, might develop tiny red spots on the roof of the mouth (petechiae). Headaches, nausea, or vomiting can also occur, especially in younger patients. Symptoms like a cough or runny nose are more indicative of a viral infection than strep throat.
When to Seek Medical Attention
Seeking medical attention for suspected strep throat is important because it is a bacterial infection that requires antibiotic treatment. Untreated strep throat can lead to serious complications, such as rheumatic fever or kidney disease. A healthcare provider can accurately diagnose strep throat through a physical examination and specific tests.
Diagnosis typically involves a rapid antigen test, where a swab from the throat is used to quickly detect the bacteria. If the rapid test is negative but strep is still suspected, a throat culture may be sent to a lab for confirmation. If diagnosed, antibiotics like penicillin or amoxicillin are commonly prescribed for a 10-day course. Completing the full course of antibiotics is important to eradicate the bacteria, prevent complications, and reduce the likelihood of spreading the infection to others. You should contact a doctor if a sore throat lasts longer than 48 hours, is accompanied by a fever, difficulty swallowing, or a rash.
