Think a 1st step would be to contact your consultant and inquire if the lack of meds is deliberate (and if so, for what reason) or just a simple oversight.
A standard practice prior to surgery (and I'm just throwing this out there as I don't know what type of meds you were on prior) is to eliminate/reduce as many of the immuno suppressors as possible prior to surgery to allow the immune system to help in the recuperation, and in case of the odd issue with surgical meds arising. It may be something as simple as consultant wanted you free of the meds before the operation, then forgot to put you back on them afterwards. OR, it might be he/she wanted to see how you progressed post surgery without... and keep in mind some of the meds are of a type that... well, if one is free of certain symptomology, then the risk of the meds isn't warranted. you know what I mean? Some of the meds we commonly take are almost more risky than the disease itself. Could be that your consult doesn't want you to be exposed to that risk until such time as their is strong evidence to suggest you need them post surgery.
After my last op, I went meds free... till my disease all came back in a flash. I don't think (but I could be totally wrong) that any of our meds 'prevent' recurrance, they just step in to treat it when we have symptoms.
Here in Canada (different than the UK's NHS, but closer than the US model)
I can walk into ANY hospital in my province and get treatment (for free). To see a 'specialist' (which is a close equivalent to your consultant) I HAVE to be referred by my family practice physician (what we call a GP, short for General Practictioner.. a doctor who practices just general medicine, and does not limit themselves to one specialty or specific area of medicine). But, I can then make my appointments at will with that specialist, or even go back to my GP and ask for other referrals to other specialists, then see any/all of the specialists my GI has referred me to. Mind you, it sounds way easier than it actually is.. For instance, I had to wait a year to see my current GI specialist for the 1st time. One of the rules of thumb here is that the longer it takes to get into see a specialist, either the better they are or at least the more popular they are. Off the point for a moment, but locally... to get in to see/have surgery an orthopedic surgeon specialist in the city here is upwards of a 2 year waiting list... but if one travels 2 1/2 hrs south of here to see an ortho surgeon there, the waiting time is only 3 months.. simply because that rural area, tho equipped with ortho surgeons and a fully equipped hospital, surgery, etc., don't have the populace to fill all the dr's time... so hard pressed city inhabitants who get impatient (no real pun intended) just put up with the commute. Just a commentary on the Canadian way of doing things.. every one has access to free health care, but its a first come, first served method with long waiting lists. This may not be the case in the UK... the commuting to other hospitals or else getting into see other consultants. You need to check with your doctor.
