subcutaneous, formed by adipocytes (i.e. the cells that store lipids).
The altered venous and lymphatic circulation resulting from the accumulation of liquids mainly causes swelling (edema) as an effect, but can predispose to other problems that affect the correct functioning of the lymphatic and blood circulation. This malfunction determines, in turn, the leakage and accumulation of liquids in the interstitial spaces (between cell and cell) of the subcutaneous tissue, which swells and increases the pressure on the surrounding tissue.
The stasis in the lower limbs due to the district slowing of the microcirculatory flow results in the sensation of swollen and heavy legs.
If the edema stagnates for a long time (ie it is not transient), it leads to the hypertrophy of the adipocytes and predisposes to inflammation.
In most cases, the tendency to retain fluids in the body is simply caused by a wrong lifestyle (sedentary lifestyle, unbalanced diet, etc.) and, with a simple correction, can significantly improve.
