Gaining Nearly 20 Pounds in a Year: Should I Worry?
Hello, I'm a 17-year-old female, standing at 5'3" and currently weighing 124 pounds. I don't have any known health issues (my slight iron deficiency has been adequately treated over the past year), nor am I on any medications besides iron supplements and occasionally Tylenol. Recently, during my annual health check-up, I was surprised to learn that my weight had increased by approximately 20 pounds; a year ago, I weighed between 104 and 106 pounds, and historically, my weight has ranged from 100 to 105 pounds, with a brief dip to 99 pounds one year. My height has been fairly stable at about 5'2" for the last five years, but it seems I have grown a little this year. Now, with my weight at 124 pounds, I'm questioning whether this change is a cause for concern or if it's within a healthy range. Physically, I do not notice a significant difference in my appearance; if anything, I feel I look healthier now compared to before when family members often remarked that I seemed underweight and fragile. Aside from this weight gain, I haven't experienced any other symptoms that would signal a problem. I might not have even realized I had gained this much weight if it weren't for the doctor's update. Up until around age 10, before puberty, I consistently fell within the higher percentiles for both height and weight for my age group, but my growth rate significantly slowed post-puberty. I faced some challenging years filled with anxiety, during which my appetite diminished, and my physical activity levels were quite low. In the last year, my appetite has returned, leading me to eat more than I did previously. Additionally, I have initiated a routine of regular exercise and cardiovascular workouts. I had hoped that the increase in activity would balance out my enhanced eating habits, but it seems that hasn't been the case. Also, I've read that insufficient sleep can affect hormone levels and contribute to weight gain. During the school year, I was getting only about three hours of sleep each night, which has me pondering if that impacted my weight as well. I'm eager to know if this weight gain could be a normal and healthy occurrence or if it warrants further investigation and potentially a dietary adjustment or other action.

It's understandable to feel concerned about a significant weight change, especially at your age. Gaining about 20 pounds in a year can occur for various reasons, and in your case, it seems linked to your return of appetite and increased physical activity. Importantly, this growth might also reflect healthy bodily changes as you transition into adulthood. Here’s what you need to consider:
Explanation
Your weight gain, while notable, doesn’t automatically signal a health problem, especially since you've mentioned feeling healthier and more energetic. At 5'3" and 124 pounds, your Body Mass Index (BMI) falls within the normal range (18.5 to 24.9), suggesting you’re currently maintaining a healthy weight. It’s normal for young adults, particularly after puberty, to experience fluctuations as your body continues to adjust.
Factors influencing your weight include:
- Increased appetite and activity: You’ve started eating more and exercising regularly, which is usually positive for both physical and mental health.
- Sleep habits: Lack of sleep can impact hormones that regulate hunger, potentially leading to weight gain. Notably, three hours of sleep at night is significantly lower than recommended.
- Psychological changes: Your history with anxiety could affect eating patterns and weight.
Next Steps
-
Monitor Your Eating Habits: Keep an eye on what and how much you're eating. Aim for a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Consider portion sizes and try to include snacks that are nutritious rather than high in sugar or calories.
-
Sleep Improvement: Prioritize getting 7-9 hours of sleep per night. This is crucial not just for weight management but for overall health and well-being. Establish a calming bedtime routine to help improve your sleep quality.
-
Maintain Regular Exercise: Continue your cardiovascular workouts but integrate strength training, which can improve metabolism and enhance muscle mass. Aim for at least 150 minutes of moderate aerobic activity weekly, alongside strength training on two or more days.
-
Reflect on Stress and Eating: Consider how emotional well-being affects your eating. If you notice fluctuations tied to stress, it may be helpful to incorporate mindfulness practices or seek support if needed.
-
Regular Check-ups: Continue with annual health check-ups to monitor your growth, nutrition, and any iron levels, staying mindful of how your body responds to changes as you age.
If you're feeling uncertain or uneasy about the weight change or if any new symptoms arise, don’t hesitate to reach out to a healthcare professional for personalized advice. Remember, focusing on overall health, rather than just weight, is key.

Persistent Leg Shaking After Months of Training
For the past seven months, I have been engaging in strength training sessions 2 to 3 times weekly, each lasting between 10 to 20 minutes. I utilize an application that guides me through a variety of exercises, including squats, calf raises, and pilates routines. Unfortunately, I’ve noticed no enhancement in my leg strength. Even during my very first calf raise, my legs tremble significantly when I lower myself back down. I have assessed my nutrition and ensure I consume around 80 to 90 grams of protein daily, considering my weight of approximately 72 kg as a young woman. Has anyone else experienced similar symptoms, or does anyone have insights into what might be causing this? I hesitate to consult a doctor about this issue, yet I'm beginning to wonder if it's time to seek professional advice.

Understanding Paroxetine Interactions with Diet
Greetings! I'd like to share my experience regarding the combination of paroxetine and diet. For the past two months, I've been using daparox (a form of paroxetine) in liquid form while adhering to a well-rounded Mediterranean diet rich in local, natural, and organic ingredients. At 22 years old, I consider myself in good health and have not encountered any significant issues with the antidepressant, nor have I had any concerns about its interaction with various substances, as I abstain from alcohol and smoking. The only sulfite-containing item I use is wine vinegar, and I do so sparingly. Recently, I’ve found myself enjoying ripe grapefruit, especially when paired with brown sugar. However, I've noticed some adverse effects, likely due to paroxetine's metabolic interactions with this fruit. It's worth mentioning that no healthcare professionals informed me about the need to avoid grapefruits. As I’ve ceased eating them, I am now concerned about whether this could have repercussions for my health. Additionally, I would like to know if there are other foods that I should steer clear of while on this medication.
Frustrations with Seeking Medical Testing
M/27, 5'8, 175 lbs, non-smoker, residing in the UK. For several years, I have been grappling with persistent symptoms that can be categorized as fatigue and various unusual sensations, such as tingling in different areas of my body. These occur even when I get a reasonable amount of rest, and at times when I shouldn’t feel tired at all. Considering my symptoms along with my family history—having relatives who suffered from severe multiple sclerosis (MS), including an uncle who passed away due to it long before I was born—I’ve been wanting to undergo testing for both MS and Epstein-Barr virus (EBV). I suspect I contracted EBV some time ago, and I've read that there may be a connection between this virus and MS. Given that testing for MS can be rather complicated, I opted to start with an EBV test, which is a straightforward blood examination. After doing my homework regarding potential antibody types detectable following an initial infection, I discovered that two key antibodies, EBNA IgG and VCA IgG, could indicate prior EBV infection status. It’s worth noting that during my childhood, I frequently fell ill, sometimes 5-6 times annually; hence, if I did contract EBV, it likely happened long ago. Eventually, resigning to the fact that I needed to consult a medical professional—after numerous visits where my concerns were disregarded—I approached a pathologist to request the blood tests. Upon presenting my specific requests, described by him as “extremely specialized,” he bluntly refused to conduct the tests, suggesting that I should “read less online.” Leaving his office, I was left questioning whether my request was truly unreasonable. It baffles me why he deemed a simple blood test too much to handle. For context, I understand that a significant portion of the population, around 90%, has EBV. This widespread prevalence should not render requesting a blood test peculiar, especially as knowledge about one’s health is important. Additionally, I had experienced multiple illnesses this year; another doctor implied I might be infected with cytomegalovirus (CMV), but again, failed to order any diagnostic testing. Now, I find myself at a crossroads. I am eager to take this test, as it holds significant importance to me, and I feel rather obsessive over it. Although I typically do not seek medical attention often, my physical condition has deteriorated over the past few years, prompting me to seek answers. However, if consulting doctors results in being dismissed for merely inquiring about a medical test, perhaps I should resign myself to living without concern for any potential health issues, be they genetic or otherwise. What’s your perspective on this situation?
