Proctitis - asacol

Diagnosed with proctitis a year ago. But for a year before this they told me it was colitis - before another colonoscopy revealed inflammation in rectum area only. Initially I was taking 2 asacol tablets three times a day, but didn't really notice much difference. Apparently they were going 'straight through me'. Now I have one suppository per day. There is a lot lot less blood than before, but it is still there sometimes. Is this normal? Or should there be no blood at all when on asacol?

Ever since I have been taking asacol I have lost a huge amount of weight, my eyes are very dry and sensitive to light, my hair is really thin, I feel weak a lot of the time and just feel like there is something missing in my body.
I am also very pale looking and people have commented on how I 'look ill'.
My skin just doesn't look right.

I'm just worried what the future holds for me really, I really don't understand how inflammation in the rectum area only can cause me to feel so weak and so thin. Is it the illness or the medication?

The GP's knows very little about this illness and the specialist is useless, you get an appointment every 6 months and never really explained anything. And now he has told me he isn't seeing me anymore and now future appointments will be with the IBD nurse.

I have a vitamin D deficiency so going to start taking tablets for this, but is there anything else I should start doing to make myself have more energy, to put on weight and better skin?

Is asacol recommended or is there better alternatives?

My diet is pretty terrible to be honest, I feel down a lot so tend to eat a lot of junk. Is there any recommended diets?

Sorry for so much information but any feedback at all will be greatly appreciated.

Also bit of a strange one, but In the last few years I am getting loads of moles on my back. I can't see how this illness or medication can cause moles but thought I would put it out there anyway!

For one thing, I recommend you get your iron/ferritin levels checked. A lot of those "weak" and fatigued feelings are often caused by being too low in iron. I've had that happen a couple of times.
