The anabolic phase can last for how long?

• A. Days
• B. Weeks
• C. Months
• D. Years

Answer: (C)

The main idea here is that the anabolic phase is a prolonged period of net tissue building after the initial catabolic stress response. After injury or major illness, the body first ramps up catabolism to mobilize energy and substrates. Once stabilization occurs, protein synthesis becomes primary again to rebuild lean mass, repair organs, and restore function. That rebuilding process is slow and ongoing, requiring sustained nutrition and rehabilitation efforts. Because muscle mass, collagen, bone, and organ structures take time to regenerate and remodel, the anabolic phase typically extends over weeks to months. In many patients with significant trauma, surgery, or critical illness, meaningful gains in lean mass and function are achieved over several months, not just days or weeks, and not in years.
