Unexplained weight gain can be frustrating and concerning. There are a few potential causes to consider if you notice your weight increasing without clear reason:
- Hormone changes - Fluctuations in hormones like cortisol, estrogen, testosterone, and thyroid hormones can lead to changes in appetite, fluid retention, and fat storage. This may happen during puberty, menopause, or due to conditions like polycystic ovary syndrome (PCOS) or thyroid disorders.
- Medications - Some prescription drugs like antidepressants, antipsychotics, diabetes medications, and steroids can cause weight gain in some people due to increased appetite, fluid retention, or other effects on metabolism.
- Aging - As we get older, we naturally lose muscle mass. This lowers our basal metabolic rate (BMR), meaning we burn fewer calories at rest. Weight gain can creep up gradually due to this age-related slowdown.
- Lifestyle changes - Significant stress, lack of sleep, less physical activity, more fast food, and other shifts in habits can promote weight gain. For example, a desk job compared to an active job or going through a stressful period.
- Medical conditions - Issues like insulin resistance, Cushing's disease, arthritis, and hypothyroidism can disrupt the body's ability to regulate weight appropriately. This allows excess fat storage over time.
If unintentional weight gain persists for a significant time without clear cause, it's wise to make an appointment with your healthcare provider. They can help pinpoint any underlying medical, genetic, or lifestyle factors through exams and testing.
Some examples of tests your doctor may consider include:
- Blood tests to evaluate thyroid, liver, and kidney function, estrogen levels, and markers of inflammation
- Checking for conditions like sleep apnea or PCOS
- Testing insulin and glucose levels to assess for prediabetes
- Screening for depression, stress disorders, or medications that could impact weight
- Imaging tests to check for issues with organs or glands
In many cases, sensible diet, exercise, and stress relief changes may help reverse or halt unexplained weight accumulation, often in combination with treatment for underlying conditions. Support from a dietitian or certified health coach at Renew Wellness can guide safe and sustainable lifestyle changes tailored to your unique needs.
The key is not ignoring significant unintentional weight changes and seeking professional help to uncover the root causes. Catching issues early vastly improves the chances of getting your weight back on track before it negatively impacts your health.
