Abstract: Using thermodynamic arguments treatment it is shown that, independently on whether Fisher renormalization changes the critical exponents near a phase transition in a constrained system or not, new corrections to scaling with correction exponents proportional to the specific heat index α appear. Because of the smallness α for the Ising, the XY, and the Heisenberg universality classes these corrections are dominant and can cause strong crossover effects. It is proven that the appearance of Fisher corrections to scaling is a quite general feature of the systems with constraints.
