Eliminating medication therapy risks! Medication-related disturbances in micronutrient balance often lead to undesirable drug effects. Long-term therapy with corticosteroids increases the risk of corticosteroid-induced osteoporosis. Thiazide or loop diuretics lead to renal losses of magnesium and potassium, which increase the risk of triglyceridemia and insulin resistance. Metformin affects the availability of vitamin B12 and promotes neurological disorders. The 4th edition of this specialized book updates all content and expands knowledge, including the influence of gut flora on the effects of medications and micronutrients, vitamin K and its potential interactions with vitamin K antagonists, as well as the numerous adverse effects of medications on vitamin D balance and the central role of melastatin channels.
