At times, parents might notice their child (who's always full of energy) showing signs of lethargy. Many just write it off as a phase, but as a parent, you should be concerned because it is not a result of just missing a few hours of sleep. This manifests itself in a number of behaviours, ranging from continuous exhaustion to being in an immobile state to overwhelming tiredness. Children with lethargy show a lack of interest in activities which, under normal circumstances, would have excited the child. 

Reasons behind lethargy -
#1 Lack of Sleep
This is the most obvious reason behind this. Lack of sufficient hours of sleep can result in continuous fatigue due to which concentrating on studies, and other such activities become a difficult task. A minimum 8 hours of sleep is essential for a growing child.#2 Malnutrition
This happens when your child does not receive the proper amounts of minerals, proteins and other vital nutrients in order to produce energy. You should always monitor your child's diet to ensure that their body is getting all the sufficient nutrients, because lack of any nutrient could lead to physical or mental problems. Healthy meals at proper time intervals are important, so don't let them skip breakfasts or let them snack on junk foods. Book an Appointment with the Best Malnutrition in India.#3 Anaemia
Lethargy is considered a symptom of anaemia, where there is a considerable reduction in the number of RBCs (red blood cells). These cells are assigned the task of delivering oxygen to different parts of the body, the lack of which causes the child to become lethargic. Deficiency of iron in the blood is the most common reason behind anaemia. Also Read: 7 Signs of Anemia during Pregnancy#4 Depression
It's rare to see Indian children suffer from depression (pressure from parents or peers is more likely). Even though depression is a mental condition, it has an effect on the child's health in the form of drainage of energy, making them feel lethargic.#5 Meningitis
Meningitis is an infection which causes inflammation of membranes that protect the brain and spinal cord from damage. In such cases, children might experience fever, sleep, lethargy and headaches. They will show reduced interest in physical activities too.#6 Fever
Fever is one of the most common reasons of this, which occurs as a result of viral infections. Here, children usually just lay in bed and restrict physical activities to a bare minimum. Also Read: Importance of Mental Health Among Youth and ChildLethargy in Babies
When it comes to babies, lethargy is harder to diagnose. But do keep in check your child's sleeping hours, and if they sleep for longer time periods, seem exhausted and less enthusiastic about playing with their toys even after waking up from their sleep; it can be because they're suffering from them. Drowsiness is also a sign of that. Do get your child checked by a doctor because he might be suffering from pneumonia, thyroid disorders, kidney dysfunction and even liver problems.Conclusion:
A lethargic toddler may be a sign of a variety of health issues, ranging from minor illness to more serious conditions, and it's important to consult a pediatrician for proper diagnosis and treatment. A lethargic child with no fever or loss of appetite may indicate an underlying health issue that requires medical attention.
