The Two Most Common Thyroid Conditions—and Their Signs
1. Hypothyroidism (Underactive Thyroid)
This condition affects your energy, metabolism, and mood. It's one of the most common reasons people are referred to Dr. Thambuluru. Symptoms include:
- Unexplained weight gain
- Cold intolerance
- Fatigue or low energy
- Constipation
- Puffiness or swelling
- Irregular menstrual cycles
"Many patients just feel 'slowed down'—and they don't realize it's hormonal," Dr. Thambuluru explains.
2. Hyperthyroidism (Overactive Thyroid)
The opposite problem—when your thyroid produces too much hormone—can make your body feel like it's running in overdrive:
- Weight loss despite normal eating
- Rapid heart rate or palpitations
- Anxiety or restlessness
- Heat intolerance
- Tremors
- Difficulty sleeping
What About Thyroid Nodules?
In the Shreveport area, Dr. Thambuluru said thyroid nodules are being found more often—not because more people have them, but because more people are getting CT scans and ultrasounds for unrelated issues.
"Most nodules are harmless," she explains. "But about 5% may be cancerous, and others may overproduce hormone, causing symptoms like palpitations, weight loss, or anxiety."
Dr. Thambuluru evaluates each case to determine whether:
- The nodule needs to be monitored
- A biopsy is recommended
- Hormone levels are being affected
- Further imaging or treatment is needed
