Suggest Treatment For Constipation
there are some particularly effective fruits that increase stool volume and may help to form softer stool. Kiwi is the best I've seen in practice but plums are also acceptable. A couple of kiwi per day make most patients feel great regarding their stool consistency. Some patients with 'weak' intestinal motility may still suffer from constipation though.
If the fruits, vegetables and salads can't make any (significant) difference then taking some lactulose seems like the next best alternative. Lactulose will make your stool softer but it can't substitute for decreased intestinal motility - if this is your main problem.
Also make sure that your drink enough water, remain physically active (every day) and try to go to the toilet at the same time each day (you should try even if you don't feel like you need to). Please keep in mind that constipation may be caused by various disorders (like tumors for example) so an abrupt onset of constipation should be investigated for the underlying cause. A long-standing constipation is different in this regard...
Finally you should try to check whether any drugs you may take (I don't see anything... there is no visible file with your history) cause constipation or not. Commonly implicated drugs include iron, certain antihypertensive drugs (amlodipine for example), opioids, etc.
I hope you find my comments helpful!
I've already suggested lactulose which can be used regularly. If softeners like lactulose fail to achieve the required results then drugs like senna or bisacodyl can be used but they can't be used every day. Using an enema is another solution when all else fails.
I hope it helps!
