Hello I have gone through your question and understand your concern. In my opinion, it is better to take a complete blood picture to rule out deficiency anemia. Weakness and fatigue can be experienced by any individual recovering from illness, as body fights with the infection throughout the illness making one feel tired without any apparent physical activity. Malaria can even cause iron deficiency anemia with weakness, fatigue as malaria causing parasite feeds on and break down red blood cells, leading to anemia. If the test results show anemia, consult a doctor or update the reports at HCM or start with iron supplements available over the counter. Get vision checked by optometrist. Weight loss is common after recovering from sickness, nothing to worry eat fresh and nutritious food, take ample of rest and take a multivitamin for quick recovery.Good luck. Hope your concern is answered. Thank you.
