Being constipated is one part of the IBS syndrome, but if the symptoms are very chronic and the gas, etc. is more than you would expect in a normally constipated person, it would be termed IBS.
But the treatment as you say is more or less the same.
The most important steps to treat constipation are: Diet
: a high fiber diet is undoubtedly the most important. Have plenty of vegetables and fuits like banana. Water
: Drinking enough water is also very important. Bowel habits
: good bowel habits including having a regular time set apart for bowel movements and not ignoring the urge for a bowel movement. Exercise
: Sedentary people suffer much more from constipation than those who exercise regularly.
Besides these measures, you can try with laxatives.
You can try initially with oral laxatives like bulk-forming laxatives like methylcellulose (Citrucel), polycarbophil (Fiberco), psyllium hydrophilic mucilloid (Metamucil), and malt soup extract (Maltsupex).
Stool softeners that are available OTC include Colace, Surfak, and pharmacy or store-branded products containing docusate. hThey are taken orally.
You can also take a stronger laxative like Bisacodyl, available OTC as Dulcolax and Correctol. It is available in oral pill form and works within 6-8 hours.
However, if you are very uncomfortable, you can use enemas
or suppositories. Examples of enemas and suppositories include Microenema, which contains docusate, Ducolax Suppository, which contains bisacodyl, and Fleet Enema, which contains sodium phosphate. Bowel movement will occur within an hour.
