Question

because gh may also reverse some effects of aging, anti - aging clinics using gh injections to delay (1) have sprung up. many people naturally stop producing gh after age 60, and this may explain why their ratio of lean - to - fat mass declines and their skin thins. gh already is the (2) treatment of choice for many aging hollywood stars who dread the loss of their youth and vitality. administration of gh to older patients reverses these declines. however, clinical studies reveal that the administered gh does not increase (3) or exercise tolerance in older patients, and a careful study of very sick patients in (4) care units (where gh is routinely given to restore nitrogen balance) found that high doses of gh are associated with increased (5). for these reasons, earlier media claims that gh is a youth potion have proven to be dangerously misleading

Explanation:

• For the first blank, since anti - aging clinics use GH to delay something related to aging, "aging" makes sense.
• For the second blank, GH is a "drug" treatment.
• For the third blank, in the context of what GH doesn't increase (compared to reversing lean - to - fat mass decline), "strength" is a logical choice.
• For the fourth blank, "intensive care units" is a common medical term.
• For the fifth blank, high doses of a drug (GH) being associated with something negative, "mortality" (death rate) fits.

Answer:

1. aging 2. drug 3. strength 4. intensive 5. mortality
