Hello and welcome to HCM,
Emphysema is probably not associated with
constipation.
Constipation can occur due to local and systemic causes.
Local causes include - bowel obstruction due to stricture, growth in colon, growth or some obstruction outside the colon compressing the colon, rectal growth etc.
Systemic causes which affect the nerves supplying the rectum like autonomic neuropathy, Parkinson's disease, multiple
sclerosis, spinal etc can also lead to constipation.
Laxatives can provide symptomatic relief from constipation, however, long term use of laxatives can lead to watery
diarrhea.
I suggest you to consult a surgeon for clinical assessment to find out the cause of constipation.
A
colonoscopy is required to look for any evidence of growth in and outside the colon.
Definitive management can only provide symptomatic relief but it is not definitive treatment.
Thanks and take care
Dr Shailja Puri
