Understanding AFib: Causes and Next Steps
Age: 20, Gender: Female, Weight: 119 lbs, Height: 5'4" No history of smoking, alcohol, or substance use. Currently not taking any medications. Medical issues include IBS, chronic migraines, and potential POTS. Hello! I’ve been utilizing my Apple Watch to monitor my heart rate throughout the day for almost a year. Recently, however, I started receiving alerts for atrial fibrillation (AFib) that I had never encountered before. This began about three weeks ago, with incidents initially recorded at 15% and then rising to 19% AFib. I maintain a healthy lifestyle, working full-time, eating balanced meals, staying active, and enjoying good sleep quality, so I'm puzzled about the sudden appearance of these AFib notifications. My physician is skeptical about the accuracy of Apple Watches, which means I can’t share my findings with her since she might dismiss my concerns. Is there any way I can reduce the risk of AFib, or should I take further steps to investigate this issue? Lately, I've been experiencing increased lightheadedness and find myself requiring more frequent breaks at work to eat and hydrate, as failing to do so leads to significant shakiness and dizziness, even with a regular eating schedule.

It’s understandable to feel concerned about the recent AFib alerts on your Apple Watch, especially coupled with feelings of lightheadedness and shakiness. Atrial fibrillation can be alarming, but there are steps you can take to better understand and address your situation.
Explanation
Atrial fibrillation (AFib) is an irregular heartbeat that can arise from a variety of causes, including stress, changes in lifestyle, or medical conditions such as POTS (Postural Orthostatic Tachycardia Syndrome), which you suspect you may have. It’s important to note that while smartwatches can provide useful data, they may not always be 100% accurate.
Your lightheadedness and need for frequent breaks could be linked to your underlying conditions such as IBS or potential POTS. These symptoms might signal that your body is under stress or not handling certain situations well, especially if you’re becoming more fatigued or dehydrated.
Next Steps
-
Monitor Symptoms: Start keeping a daily log of your AFib alerts, lightheadedness episodes, how you’re feeling throughout the day, and any activities that may trigger these symptoms. This might give you clues about possible patterns.
-
Hydration and Nutrition: Ensure you are adequately hydrated and consuming balanced meals throughout the day. Given your symptoms, consider increasing your fluid intake and electrolytes (like from sports drinks) if you’re sweating or physically active.
-
Avoid Triggers: Identify and avoid any known triggers that may contribute to your symptoms, such as caffeine, stress, or large meals that might exacerbate your IBS.
-
Regular Breaks: Continue taking frequent breaks at work, especially if you start feeling shaky. Standing or sitting upright can help improve blood flow, especially if you suspect POTS.
-
Consult a Specialist: While your current doctor is skeptical, it may be worth seeking a second opinion from a cardiologist or an electrophysiologist who specializes in heart rhythm disorders. Bring your symptom log with you and express your concerns about both the AFib alerts and lightheadedness.
-
Stress Management: Engaging in relaxation techniques like deep breathing, yoga, or meditation can help manage stress, which may contribute to AFib episodes.
By following these steps, you can actively participate in your health while gathering important information to share with a healthcare professional. Please remember to prioritize your well-being and keep a close eye on persistent symptoms. Don’t hesitate to seek help if things worsen or if you have any major concerns.

Concerns Regarding Ovarian Cysts
Greetings, everyone. Three months ago, a mass was detected in my ovary, and I opted to have it closely monitored instead of immediately proceeding with surgery. A recent examination has yielded the following results: The cyst measures 25 mm by 21 mm by 22 mm, with an average size of 23.0 mm and a volume of 6.287 cm³. It is identified as an anechoic, unilocular cyst showcasing circumferential vascularity, rated 2 in internal vascularity. Its size appears consistent with the previous assessment. There may be three irregular projections observed, whereas the last evaluation only identified a single papillary projection within the scanning limits, detailed as follows: 1) Base measuring 9.6 mm with a height of 7 mm; 2) Base at 11 mm with a height of 7.3 mm; 3) A smaller projection with a base of 2 mm and a height of 1.3 mm. It should be noted that my medical history includes a salpingo-oophorectomy due to pre-cancerous cells, along with a right salpingectomy. Previously, my right ovary was noted to have a unilocular cyst measuring 22 mm by 12 mm by 19 mm, which also presented a papillary projection (base approximately 8 mm and length 17 mm), again rated at 2 for vascularity. At 44 years of age, I am currently on ryeqo to manage fibroids and endometriosis, a treatment I have been following for the last 16 months. My main concern is understanding why the number of papillary projections has changed, specifically how it went from one to three. Should I be alarmed by these findings? My specialist appointment isn't scheduled for another three weeks, and I would greatly appreciate any insights or advice you could offer. Thank you for your assistance!
Feeling Anxious About My Health
I'm a 17-year-old male experiencing distressing symptoms that lead me to suspect I may have a urethral stricture. It often feels as though there’s urine trapped in my urethra, and I feel a constant urge to urinate, which is incredibly frustrating. This situation has left me feeling quite fearful, especially after falling three times on my back while playing soccer. I've been taking SSRIs for about a week now, but I haven't noticed any improvement in my condition. The onset of this issue coincided with my recent use of creatine, after which I experienced an unusual episode where I urinated continuously for nearly a minute upon waking. Now, I find myself worrying that I may have caused some harm to my bladder and am concerned about the possibility of a stricture. At just 17 years old, this situation is profoundly affecting my quality of life, leading to feelings of hopelessness and suicidal thoughts due to the pain I am enduring. A few weeks ago, I took a UTI test, which came back negative, so I can rule that out. I have my suspicions regarding a possible STI, but that seems unlikely since my last sexual encounter was over eight months ago. I recently underwent an ultrasound, which indicated that my bladder wasn't overly full at the time of the test. Although I was required to pee during the procedure, the results showed that my bladder was completely empty. Despite this, I continue to feel a persistent urge, particularly in the urethra, where I also experience pain upon applying pressure to the tip. This discomfort began about a week ago, and it’s incredibly unsettling.
Experiencing Sudden High Heart Rate Episodes
Hello everyone, I find myself in urgent need of support and insights regarding a concerning issue I’m facing. I’m a 20-year-old woman who has recently begun encountering episodes characterized by a significantly elevated heart rate, occurring even while at rest. These episodes seem unpredictable, and during them, I can feel my heartbeat intensely, as if it might burst from my chest. This has occurred four times now, with today’s episode being the most alarming. While attending class, the sensation returned, and my heart rate surpassed that of previous instances. It thumped vigorously and rapidly, leaving me anxious. Thankfully, I’m feeling somewhat better now, but the worry continues to linger. I don’t experience pain in my chest and I’m not having trouble breathing, yet I occasionally feel faint. Additionally, my hands were shaky afterward. I’ve also observed a deterioration in my sleep patterns since these occurrences started. Generally, I sleep soundly through the night, but now I find myself awakening once or twice. To clarify, I do not consume alcohol, take drugs, smoke, or drink caffeine, and I’m not on any medications either. Last week, I consulted with my doctor, and some tests are on the horizon. I had a blood test done (awaiting the results) and a Holter monitor test is in the works. Has anyone else experienced something similar, or perhaps had similar episodes in the past? What did you discover to be the underlying cause? Should I be concerned about the potential severity of this situation? I am genuinely anxious about it.

Feeling Unwell After My Trip to Thailand
Greetings! I'm a 21-year-old woman, standing at 5 feet 7 inches and weighing 170 pounds. I just returned from a two-week visit to Thailand three days ago. During my flight, I began to experience a really uncomfortable sore throat, which I initially attributed to dehydration. Now that I've been back for three days, my condition seems to be deteriorating. My tonsils are extremely swollen and inflamed, and I'm dealing with a sore throat and a significant amount of mucus. While I don't think I have a fever, I'm feeling aches throughout my body and experiencing chills that mimic feverish symptoms. Considering I've just traveled internationally, should I be worried enough to seek medical help? I'd hate to panic unnecessarily, as I'd prefer to tough it out, but I'm really not feeling well at all.
