Should I Weigh Myself in Clothes or Without for Accurate BMI Calculation?
I’m a 21-year-old female, standing at 5 feet tall and weighing 98 pounds, with no health issues to report. During my visits to the doctor, they take my weight and use it to determine my Body Mass Index (BMI) while I’m fully dressed. To keep my calculations consistent at home, should I also weigh myself in the same outfit? My goal isn’t significant weight loss; rather, I simply wish to ensure that my weight and BMI calculations are as precise as they can be.

To calculate your BMI accurately, it's best to weigh yourself in the same type of clothing each time. This consistency helps ensure that any fluctuations in your weight are due to changes in body weight, not variations from clothing.
Explanation: BMI is calculated using your weight in kilograms divided by your height in meters squared. While it's true that your weight can vary depending on what you're wearing, the most important factor is maintaining consistent conditions when tracking your weight over time. Weighing yourself in similar clothing (or at least weighing yourself in a usual outfit) will yield more reliable comparisons.
Next Steps:
- Weigh Yourself Consistently: Choose a specific outfit or type of clothing that you will wear each time you step on the scale (e.g., light workout clothes or pajamas).
- Stand on the Scale at the Same Time: Weigh yourself at the same time of day, preferably in the morning after using the bathroom, to reduce variations due to food and fluid intake.
- Record Your Measurements: Keep a log of your weight along with the dates to monitor any trends over time. This will help you see any gradual changes in your weight or BMI in a meaningful way.
By following these steps, you'll be able to track your weight and BMI more accurately, and this can help you stay aware of your health without focusing solely on weight loss. If you have further questions or need additional support, feel free to ask!

Phentermine Inquiry
I'm reaching out on behalf of a friend who feels a bit anxious about this situation and couldn’t bring himself to ask directly. He's a 20-year-old male, standing at 5 feet 8 inches tall. Initially weighing 175 pounds, he began a regimen of Phentermine, taking 30 mg each day, and has successfully dropped down to 145 pounds over the course of nearly three months. However, he has decided to discontinue the medication due to concerns about its long-term implications on his health. Does anyone with knowledge of this medication have insights regarding potential long-term effects, especially since he has ceased its use? He hasn't experienced any side effects during his treatment, but he's heard accounts of long-term users developing serious cardiovascular issues years after stopping, sometimes necessitating surgical procedures. Please share your thoughts on his situation and whether he can expect to be alright moving forward.
Experiencing a Burst Vein Post-Blood Draw: How Long Should I Avoid Strenuous Exercise?
I recently had blood drawn, and for the first time, I experienced a vein rupture. Typically, I refrain from intense workouts for a day after having blood taken, but this situation has me concerned. From my online research, it seems the healing process could take a minimum of ten days. I routinely include exercises like push-ups and planks in my fitness regimen. Is it really necessary to refrain from these activities until my arm has fully recovered?
Is It Safe to Lift Heavy Weights Without a Belt?
I’m an 18-year-old male who has just bounced back from an injury. According to my physician, my issue stemmed from my sacroiliac joint being misaligned for several years, which I believe contributed to a difference in leg length that ultimately resulted in a groin strain. In light of this experience, I've become increasingly cautious about my lifting practices, though the injury wasn’t directly related to my weight training. Now, I’m curious about whether it’s advisable to lift weights without using a belt, particularly in terms of preventing hernias. I’ve heard that hernias might arise from the heightened intra-abdominal pressure that occurs when bracing the core during exercises like squats and deadlifts. Without a belt, this pressure is directed against the abdominal wall, increasing the risk of organs pushing through. So, is it possible to lift safely without a belt while avoiding the risk of developing a hernia? If the answer is no, are there alternatives I can explore (other than investing in a lifting belt) to mitigate this risk? I greatly appreciate any insights on this matter, as it's been on my mind and I'm eager to find clarity.
Addressing Rib Displacement After Chest Workouts
Approximately a month ago, I (32M) began to notice discomfort along my left side, specifically in the thoracic region—more prominent in the front and somewhat in the back—after my typical chest workout involving moderate weight training. Additionally, I observed that one of my left lower ribs, likely around the eighth rib, appeared to protrude further outward than what I considered normal. Unfortunately, in the weeks following this incident, I've realized that the rib hasn’t reverted to its usual position, and it tends to become increasingly painful after I engage in chest exercises. I’m seeking advice on how to manage this situation. While it isn’t critical enough to warrant surgical intervention in my opinion, the discomfort is quite distracting and prevents me from executing my usual workout routine effectively. To provide some context, I am right-handed, which translates to my left side being slightly weaker.
Concerning Inward-Turning Foot
At seventeen, I find myself grappling with several health conditions; I’m managing postural orthostatic tachycardia syndrome (POTS), hypermobility, and adenomyosis, and I'm currently at a weight of 240 pounds. One of the most challenging issues I face is that my left foot turns inward. Although I can force it into a straight position, it feels extremely uncomfortable and causes me to lose my balance. This peculiar alignment has been present since my infancy, as it was first recognized when I was around two years old. I suspect it stems from birth, especially because there was no injury involved. In prior physical therapy sessions, my therapist merely described my condition as "inward-turned foot with no known origin," but I assure you, it isn't something I'm doing intentionally; that's simply the way my foot behaves. This issue has led to a noticeable limp. I’ve been advised to perform a towel exercise, attempting to maneuver my foot, but the results have been lackluster. I'm curious about what might be responsible for this problem. Is there a solution? The embarrassment of limping has become overwhelming; I often face ridicule, and I would gladly wear a brace for an extended period if it meant alleviating this issue. It truly feels odd!
