Swollen lymph nodes—those small, tender bumps you can feel around your neck, armpits, or groin—are a red flag. These nodes act like filters, and when the immune system is fighting a virus, they enlarge.
Key points to monitor:
- Persistent swelling for more than 2 weeks.
- Accompanied by fever or night sweats.
- Often painless, making it easy to ignore.
Sudden Weight Loss and Digestive Issues
Some people notice rapid, unexplained weight loss, diarrhea, or nausea. These digestive issues can stem from the immune system struggling to fight off infections.
- Weight loss: More than 5% of body weight over a few months without diet changes.
- Digestive distress: Persistent diarrhea, stomach cramps, or vomiting.
Being alert to these subtle but persistent changes can be lifesaving.
Night Sweats and Chills
Excessive night sweats, soaking pajamas or bed sheets, often combined with chills, are another symptom many people report. Unlike regular sweating from heat, these episodes happen regardless of room temperature and disrupt sleep.
