High dose triphala, lactulose, chlorella doing little for constipation.

Hi,

I have problems with fatigue, bloating, constipation amongst other things.

Tried loads of things, nothing seems to help.
Been recently adding 45ml of lactulose and 2.5g of chlorella with each meal every day and 4 grams of triphala (capsule) at night.

The triphala seems to have done nothing after 1.5 weeks and the rest have only boosted me up to almost every other day from previously every 5 days.

Anyone know what could be causing this constipation and seemingly resistance to constipation relief remedies.

It is not painful, generally minimal flatulence, I just have no urge to go, it feels almost as if my colon is shut down...

As always any help is much appreciated.
