Experiencing Dizziness Upon Standing
As a 30-year-old female, I often feel faint and my sight dims whenever I rise to my feet. This unsettling sensation typically forces me to either sit down or recline until my vision stabilizes. I've been dealing with this issue for a year or two now. In one instance, I attempted to push through it, which resulted in me collapsing and striking my desk, causing my drink to spill everywhere. Does anyone have suggestions about what might be happening? I maintain an active lifestyle, partaking in activities like Taekwondo and cheerleading, eat a balanced diet, and I am not a parent. My medical history includes a well-managed diagnosis of hypothyroidism, narcolepsy type II without cataplexy, and obstructive sleep apnea. Additionally, I have pectus excavatum and am prescribed a beta blocker due to my rapid heart rate.

It sounds like you're experiencing a form of dizziness known as orthostatic hypotension, which often occurs when you stand up quickly. This can be particularly concerning given your history of medical conditions. Let's unpack your symptoms and consider what steps you can take to manage this situation effectively.
Explanation:
When you change positions from sitting or lying down to standing, gravity pulls blood toward your legs. Normally, your body compensates by adjusting your heart rate and blood vessel diameter to maintain blood flow to the brain. In some cases, this adjustment doesn’t happen quickly enough, causing feelings of faintness, dim vision, or even fainting.
Factors that may contribute to this include:
- Hydration levels: Dehydration can exacerbate these symptoms.
- Medication effects: Your beta blocker may play a role in how your blood pressure responds when you stand.
- Thyroid Function: Since you have hypothyroidism, fluctuations or suboptimal management of this condition might also influence your symptoms.
Additionally, conditions like obstructive sleep apnea can lead to overall fatigue and may affect your cardiovascular health.
Next Steps:
-
Stay Hydrated: Increase your fluid intake, particularly water, as dehydration can worsen orthostatic symptoms.
-
Change Positions Slowly: When you stand up, do so gradually. Move from lying to sitting, and then sit a moment before standing. This slow transition can help your body adjust better.
-
Monitor Your Blood Pressure: If possible, check your blood pressure when transitioning from sitting to standing. This can guide you on patterns and whether there's significant hypotension.
-
Consider Diet Modifications: Increase salt intake slightly, but only if advised by your doctor, as sodium can help retain fluid and increase blood volume.
-
Wear Compression Garments: Consider using compression stockings, which can help improve circulation and reduce blood pooling in your legs.
-
Keep a Journal: Document your symptoms, daily activities, dietary intake, and any specific triggers you notice. This record can help to identify patterns and guide management strategies.
If symptoms persist or worsen, it’s essential to consult with your healthcare provider, especially to evaluate your beta blocker dosage and assess your thyroid function. It's good that you're active and healthy otherwise; maintaining communication with your healthcare team is crucial to ensure your treatment remains effective. Please take care!

Worries About Nighttime Bowel Movements
I am a 33-year-old male dealing with seasonal allergies and anxiety regarding my health. I don’t smoke or drink alcohol. While I haven’t received an official diagnosis, I have reasons to believe I may suffer from IBS, specifically the diarrhea-predominant type. Additionally, I experience mild to moderate reactions to dairy products, fatty meals, and overeating bread. Recently, my sleep schedule has shifted; I tend to stay up until about midnight or 1:30 AM, and I usually have a bowel movement around 11 PM almost every night. Over the years, I have averaged between one to three bowel movements daily, occasionally leaning towards looseness or diarrhea. This routine includes a bowel movement in the morning and a second one in the late evening. If I skip that late-night trip to the bathroom, I may find myself waking up with the need to go. In the past seven weeks, I've experienced four episodes of nighttime bowel movements. Two of these incidents occurred within a week and were triggered by consuming the same type of dinner. Another instance followed a meal consisting of various foods I suspect could be triggers. On those nights, I woke up with some abdominal cramps prompting an urgent need to go to the bathroom. This past week, two of these nighttime awakenings came after I drank a lot of water before bed, and upon heading to the restroom, I also felt the need to have a bowel movement. Thankfully, there was no accompanying pain. I'm curious about how alarming this situation might be, particularly regarding the fear of bowel cancer. Notably, three out of the four episodes followed a dinner where I had a large steak, and I’m wondering if that detail matters. During my physical examination in March, my doctor assessed that my symptoms were not a cause for concern, explaining that loose stools are generally not indicative of bowel cancer. Here's to hoping for some reassurance on this matter.
Calf Muscle Biopsy Report - Minimal Discomfort the Next Day
Greetings, I'm a 30-year-old male, standing at 5 feet 11 inches, weighing 190 pounds. Yesterday, I underwent a muscle biopsy on my right calf. The procedure was necessitated due to suspicions of Myositis, which were hinted at by an MRI. Additionally, I have an MRI planned for my lower back to exclude any potential nerve complications, as my EMG test yielded unexpected results. The incision measures approximately three inches and has resulted in some noticeable bruising. Surprisingly, I experience little to no discomfort unless I balance on one leg, and even then, the sensation is very mild. Is this typically what one should expect? I had been advised to prepare for significant pain in the initial days, and although the wound appears rather alarming, the absence of pain is concerning. I worry that if there is indeed a nerve issue, I may inadvertently injure myself due to my body not signaling discomfort as it normally would.
Confusion Over Stool Appearance
I am a 26-year-old male, standing 6 feet 2 inches tall and weighing 280 pounds, and I abstain from alcohol and tobacco. I am uncertain whether what I'm seeing in my stool is blood or merely remnants of food. Last night, I consumed watermelon, and today I have noticed red fragments in my bowel movements. I've been experiencing significant constipation lately. Upon examination, I found that I could isolate these red pieces from the stool; they didn’t smear much and were somewhat solid, allowing me to roll them between my fingers. The only times I've felt any relief have been after drinking coffee or using a laxative. Additionally, I've been experiencing a slight, persistent pain in my lower right back; while not severe, it is certainly bothersome.
Unusual Sharp Discomfort Behind the Eyebrow During Flight
As a 23-year-old female, I had a peculiar experience with a sudden, intense pain located just behind my eyebrow while flying. This incident occurred nearly two years ago, and since then it hasn’t reoccurred, so I’m not particularly anxious about it. However, I've often found myself pondering what might have caused such a sensation, which led me to seek answers. During a short flight of about an hour and a half from London to Norway, I felt completely fine for most of the journey. However, as we began our descent, an abrupt, sharp pain shot through my eyebrow area. It was so intense that I initially feared I had somehow injured myself. Despite closely inspecting my eyebrow with my phone's camera, I discovered no visible injury, yet the pain intensified to a level that became nearly intolerable. I began to worry about navigating a foreign healthcare system in Norway without any knowledge of it. Touching the affected area made the discomfort even more pronounced; it felt similar to the stinging sensation of waxing. Remarkably, once we touched down and within a mere ten minutes, the pain completely disappeared. This episode was unlike anything I had experienced either then or prior during air travel. I suspect it may have been akin to a migraine triggered by shifting air pressure, although I have never had an eyebrow-centric headache like that before. I do suffer from chronic sinusitis, which could potentially be a contributing factor. Regardless, I have always found this occurrence fascinating and thought that perhaps you could shed some light on it.
Persistent Throat Mucus for Several Months
I'm a 16-year-old male, standing at 5'9" and weighing 150 pounds. For several months now, I've been battling with persistent mucus lingering in my throat. I've consulted my doctor numerous times, to the point where I worry that I may be overdoing it. It feels as though my concerns are being brushed off, with the recommendation to simply continue my medications. I have a strong hunch that my anxiety is at play here. Throughout my life, I've struggled with anxiety and OCD. Although I experienced some improvement after I started exercising, I still deal with lingering anxiety. About a month ago, my anxiety escalated to the point where it severely disrupted my sleep. This lack of sleep only increased my anxiety, creating a vicious cycle. I can’t recall exactly how I managed to calm myself down, but once I did, I finally found some rest. Another odd issue I've encountered is an inability to sneeze, which I suspect might also stem from anxiety. There have been moments when I’ve been preoccupied with tasks, only to suddenly sneeze out of the blue, which makes me think that mental stress is the underlying cause of my various symptoms. I recently received my lung X-ray results, and thankfully, everything appeared normal. My doctor had previously prescribed antibiotics to eliminate any possible throat infection. While I adhered to the treatment and the mucus seemed to disappear during that time, it reemerged once I finished the six-day course. Now I'm left questioning whether my ongoing mucus issue is purely psychological or if there might be a genuine physical ailment at play—or perhaps a combination of both. Feeling a bit hopeless, especially with my doctor seeming to dismiss my concerns, I’m reaching out here on Reddit in search of support and advice. What might help clarify whether this is just psychological, or an actual physical issue? I'm truly desperate for some answers and any guidance would be immensely appreciated.
