Feeling unusually tired or drowsy throughout the day can be frustrating and may signal an underlying issue. At Queen Peoples Pharmacy in Calgary, Alberta, we want to help you understand some common reasons behind excessive sleepiness.
Possible causes include:
- Poor sleep quality – Interrupted or insufficient sleep can leave you feeling drained.
- Sleep disorders – Conditions like sleep apnea, insomnia, or restless leg syndrome may disrupt rest.
- Medications – Certain prescriptions or over-the-counter drugs can cause drowsiness as a side effect.
- Lifestyle factors – Lack of exercise, poor diet, or high stress can all contribute to fatigue.
- Medical conditions – Issues such as thyroid problems, anemia, or diabetes may lead to excessive sleepiness.
If you’re struggling with persistent drowsiness, our pharmacists can review your medications and provide guidance on lifestyle changes or recommend when to seek medical advice. Call us at 587-441-4222 or visit queenpharmacy.ca for personalized support.
