Understanding Sternum Movement When Rising from a Lying Position
I’m 6 feet tall and weigh 220 pounds. Recently, I've observed an interesting change in my body mechanics while getting out of the bath. When I’m lying flat, everything seems normal. However, as I place my hands on the sides and push myself up, my sternum noticeably sticks out. This only happens in that particular scenario; at all other times, my sternum appears to be in its usual position. Curiously, this is something I've been aware of for the last couple of months, whereas prior to that, I never really gave it any thought. Although it appears a bit pronounced, I have no medical expertise beyond basic first aid and am keen to learn about the underlying muscular dynamics at play in my body as I transition from lying down to an upright position.

It sounds like you’re noticing a change in your body mechanics when transitioning from lying down to sitting up, especially concerning the position of your sternum. This can be linked to how your muscles, ligaments, and even your posture interact during that movement.
Explanation:
When you lie down flat and then push yourself up, your abdominal and chest muscles are engaged to assist in lifting your torso. The sternum (the bone in the center of your chest) can appear more noticeable due to the way your ribcage expands or contracts during this motion. Factors such as muscle tone, body weight, and posture can influence this appearance.
If this is the only time you've noticed this change, it might be due to temporary muscle engagement or positioning rather than an underlying health issue. It's not unusual for some people to experience changes in their body's mechanics as they gain awareness of how they move.
Next Steps:
-
Observe Posture: Pay attention to your posture when moving from lying down to sitting up. Ensure you're using your core muscles effectively without straining your neck or back.
-
Strengthening Exercises: Consider incorporating gentle strengthening exercises for your core (such as planks or seated leg lifts) to enhance muscle tone, which may help in stabilizing your posture during movements.
-
Breathing Practice: When rising, focus on your breath. Engaging your diaphragm can support your chest and ribcage, which may help your sternum appear more aligned.
-
Monitor Changes: Keep track of how your body responds in different scenarios. If the prominence of your sternum continues or is accompanied by any discomfort or changes in breathing, it would be beneficial to explore this further.
-
Stay Engaged: Continue to pay attention to your movements and how they feel. Being mindful of your body can help you adapt your techniques and understand the changes you’re experiencing.
If there’s any further concern or if you notice additional changes, don't hesitate to seek a professional evaluation. Understanding your body is a great pursuit, and these adjustments may enhance your overall wellness.

Concerns About My Mother's Health
My mother, who is 51 years old, weighs approximately 60 kilograms, and stands around 5 feet 4 to 5 feet 5 inches tall, has some health issues that worry me. While I am uncertain about all of her medications, I do know she takes something to manage high blood pressure and also uses prescribed antihistamines. Additionally, she has a troubled past with alcohol abuse. In January of last year, my brother had to call an ambulance for her while I was away from home. He reported that she was displaying manic and hysterical behavior, including throwing objects and banging her head against the wall, an incident which led to her needing stitches on her tongue. In the days prior, she had been bedridden, lacked appetite, slept excessively, and appeared extremely fatigued. To help, I asked my aunt, who lives nearby, to check in on them while waiting for the ambulance. She reported that my mum seemed fine at that moment. Upon arriving at the hospital, the doctors discovered that her sodium levels were critically low—this stands out as a significant detail that I recall. Medical professionals suspected she experienced a seizure, leading to a week-long hospital stay during which numerous blood tests, MRIs, CAT scans, colonoscopies, and a dental examination (due to her gingivitis) were conducted, yet they could not determine the underlying cause, especially as she had no prior history of seizures. Additionally, her arms and legs appeared quite thin. After her release, her health has remarkably declined; she's been frequently ill—at least once every two weeks or several times each month, she finds herself in bed for up to 48 hours experiencing severe shaking and vomiting. Although she has occasional dizzy spells, they don’t match the chaotic episode my brother witnessed last year. I'm really concerned about her wellbeing, as it seems her condition has only worsened since leaving the hospital. Does anyone have any insights or suggestions on what might be happening?
