Hello dear,
The causes of
constipation can be:
1. Any pathology/ sub acute obstruction in the Gastrointestinal tract
2. Functional cause- due to decreased gastric motility
3. Less intake of fluids & fiber rich diet.
4. Parasitic/ Amoebic infection.
5.
Hormonal & Metabolic causes, etc.
Though symptomatic relief can be obtained by intake of Laxatives, their regular use is not advised.
And as long as the underlying cause is not treated, symptoms will keep recurring.
So, kindly consult a Pediatrician/ Gastroenterologist & get a proper physical examination done.
Investigations like
complete blood count,
Ultrasound scan of abdomen,
Colonoscopy & contrast studies will be helpful to rule out any pathological cause for his symptoms.
There is no need to worry, your grandson will be fine.
Till then, give him healthy nutritious diet & maintain adequate hydration status.
Wishing him a good health.
Take care.
