Final answer:
Sandra's secondary obesity could be caused by an underlying medical condition such as polycystic ovary syndrome (PCOS) or the use of certain medications, like antihypertensive drugs. Secondary obesity differs from primary obesity, which is mainly caused by a combination of excessive calorie intake, inadequate physical activity, and genetic susceptibility.
Step-by-step explanation:
Sandra, age 28, has secondary obesity, which is a type of obesity resulting from an underlying condition or the use of certain medications. One possible cause for her secondary obesity could be polycystic ovary syndrome (PCOS), which is associated with weight gain and insulin resistance, leading to obesity. Another potential cause is the use of certain medications such as antihypertensive drugs, which can sometimes contribute to weight gain. It is also important to note that conditions like hypothyroidism and Cushing's disease are other examples of medical conditions that can lead to secondary obesity.
General causes of obesity also include genetic susceptibility, excessive food intake, and inadequate physical activity; however, these factors usually contribute to primary obesity. In Sandra's case, it's important to investigate the specific underlying factors contributing to her secondary obesity, which might require a medical evaluation for conditions like PCOS and a review of her medication regimen to properly address her weight management.
