DX Keto After a stomach reduction operation you have to take blood thinners for a while to reduce the risk of thrombosis (a blood clot that gets stuck somewhere). A blood clot in the lungs (pulmonary embolism) can be life-threatening.Leaks can occur around stitches and staples and this can lead to peritoneal infection, for example. If this happens, a viewing operation is required.After surgery, there is always a risk of (internal) after bleeding. Sometimes you have to undergo surgery again. https://www.baysidepetroleum.com/ https://www.facebook.com/DX-Keto-103650841113292/
