Final answer:
Chronic activation of Maya's HPA axis suggests she is likely to face gastrointestinal issues (option C) due to prolonged exposure to cortisol, which can lead to various health complications.
Step-by-step explanation:
Maya's activation of the hypothalamic-pituitary-adrenal (HPA) axis over many weeks is indicative of chronic stress, which has various physiological effects due to extended release of cortisol. Chronic or long-term activation of the HPA axis can lead to a range of health problems. Given the options provided, the most likely problem Maya would face after chronic HPA activation is gastrointestinal issues (C).
Prolonged stress and high levels of cortisol can significantly weaken the immune system and may lead to various issues such as gastrointestinal problems, fatigue, depression, and even cardiovascular problems. However, cardiovascular improvements (A), enhanced cognitive function (B), and increased muscle strength (D) are not typically associated with chronic HPA axis activation; rather, they are more likely to be compromised due to the sustained physiological stresses associated with elevated cortisol levels.
