Your weakness is likely a combination of both your lifestyle habits and low hemoglobin. Low hemoglobin (anemia) directly reduces oxygen flow in your body, causing fatigue. Autrin (an iron and vitamin supplement) is prescribed to help rebuild your blood levels, while Paracetamol manages pain but doesn't cause ongoing weakness. Additionally, skipping meals, poor sleep, and staying indoors deprive your body of essential nutrients, restorative rest, and Vitamin D, worsening your exhaustion. To regain your energy, it is important to continue your Autrin as prescribed, eat regular balanced meals, establish a sleep routine, and get a bit of daily sunlight.
