I’m really glad you listened to your body and took some time off. Being diagnosed with anemia can definitely affect energy levels, endurance, and recovery, so easing back into training is important.
When you return to the gym, I’d suggest starting with lighter weights and slightly lower volume for the first couple of weeks. Focus on controlled reps, good form, and avoid pushing to absolute failure right away. Anemia can sometimes cause fatigue, dizziness, or shortness of breath, so if anything feels off during a workout, it’s best to stop and rest.
Make sure you’re also supporting recovery outside the gym getting enough sleep, staying hydrated, and following whatever nutrition or supplementation your doctor recommended (iron, vitamin B12, etc.). That will make a big difference in how quickly your energy levels return.
Definitely recommend being under medical supervision if you do decide to train
