More appearance of blue veins running down arms and stomach?

Probsbly ok. Assuming you are losing large amounts of weight and do not have serious medical problems such as liver disease or hiv, it is probably just superficial veins that have become more noticeable. Discuss with promary md at next examination.
Liver check. Increased 'blue veins in the stomach' (caput medusa) could be a sign of liver disease (cirrhosis) so your liver should be checked.
