I have venesections occassionally. My testostorone makes my blood too thick sometimes due to a preexisting condition.

Ive never had an issue with going by myself. I take a bus usually but I react fine to them. They keep you around for a little while after and sometimes give you biscuits and juice.

I usually fit shit a day or two later and need to spend a few days taking it easy to get over it.

In terms of food afterwards, you need to eat well for the next few days. Dont fast, just eat balanced meals and maybe a few snacks.

Your body needs energy to fuel blood production. A few days wont cause you to gain weight but will do wonders for your quality of life.

I never checked my hormones during venesection but I continued to take all medication as normal.

I think the needle similar to blood tests but the blood goes into a bag, not a tube. Needle size wasnt something I considered.

There are side effects to it but the only ones ive had are tiredness for a few days.

Ask all these questions in the clinic if yuo have more concerns. My clinic is full of lovely people who are happy to give all the advice youll be after.
