Experiencing Elevated Heart Rate and Other Symptoms: Seeking Advice
I am a 23-year-old male, weighing 119 kg and standing at 187 cm. For the past week, I've been dealing with several concerning symptoms, including fatigue, mental fog, and diarrhea starting last Friday, followed by episodes of dizziness from Monday onward. Out of frustration with my fatigue, I decided to monitor my heart rate with my Apple Watch and noticed a recurring pattern: my heart rate consistently exceeds 100 bpm every night, typically during brief intervals. To illustrate, last night, my heart rate fluctuated between 92 bpm and a high of 137 bpm from 2:30 AM to 4:21 AM, after which it dropped to 40-45 bpm until I woke up. While this spike varies in duration, it's usually between 15 to 45 minutes. Additionally, I’ve been experiencing unexplained muscle aches and soreness for some time, despite not engaging in any strenuous activities regularly. It’s worth mentioning that I do not feel any chest discomfort or tightness; my muscle aches alleviate with movement or distraction. I also haven't encountered any respiratory difficulties. On another note, I've been dealing with significant acid reflux issues lately, for which I was prescribed Omeprazole 20 mg. I took it daily for two weeks, then switched to taking it every other day for another two weeks before discontinuing it two weeks ago. I haven't faced many acid reflux incidents since then, but I do continue to experience gas, frequent burping, and diarrhea. The mental impact of these physical symptoms has been considerable. As someone who tends to overthink and ruminate on "what if" scenarios, I find myself increasingly anxious. I wonder if this mental strain could be contributing to my physical symptoms. I have a scheduled appointment with my doctor next Monday to further discuss my health concerns. However, I am eager to know if there are any immediate signs or symptoms that may necessitate a visit to an emergency medical facility. If further details are required for better understanding or insight, please do not hesitate to ask.

It sounds like you're experiencing a range of concerning symptoms, and it's great that you've scheduled a visit with your doctor to discuss these issues. Here's a summary of your situation and some actionable advice while you await your appointment.
Main Points
Your symptoms of elevated heart rate, fatigue, dizziness, diarrhea, muscle aches, and anxiety are interconnected and may have multiple causes. It’s important to recognize serious symptoms and manage your current discomfort as you prepare to see your healthcare provider.
Explanation
-
Elevated Heart Rate: A resting heart rate above 100 bpm (tachycardia) can be influenced by factors such as anxiety, dehydration, or even your current physical state. Episodes during sleep may relate to stress or anxiety, especially if they coincide with feelings of fatigue and mental fog.
-
Fatigue and Mental Fog: These can frequently arise from anxiety, poor sleep, or physiological stress. It's not uncommon for physical symptoms to exacerbate feelings of anxiety.
-
Digestive Issues (Diarrhea & Acid Reflux): Stress and anxiety can significantly impact your gastrointestinal system, leading to symptoms like diarrhea and increased burping or gas. The cessation of Omeprazole might also contribute to the return of digestive discomfort.
-
Muscle Aches: These can stem from tension, anxiety, or even dehydration. They might also be a symptom of stress or a possible response to your body’s overall state of distress.
Next Steps
Here are prioritized actions to take that may help alleviate your symptoms while also preparing for your doctor’s appointment:
-
Monitor Symptoms: Keep track of any new or exacerbated symptoms, such as increased heart rate, dizziness, or changes in your digestion. Note when they occur and any potential triggers.
-
Hydration & Nutrition: Ensure you're drinking enough fluids, as dehydration can elevate heart rate and lead to fatigue. Consume a balanced diet with plenty of fiber to help with digestive symptoms.
-
Relaxation Techniques: Practice deep breathing, mindfulness, or gentle exercises like yoga or stretching to help manage anxiety and muscle tension. This could help ease both mental and physical symptoms.
-
Sleep Hygiene: Focus on establishing a regular sleep routine to improve rest quality and help reduce fatigue, aiming for a consistent bedtime and wake-up time.
-
Emergency Signs: If you experience any of the following, seek immediate medical attention:
- Persistent dizziness or fainting
- Severe headache or visual changes
- Sudden shortness of breath or chest pain
- Rapid heart rate continues, or you feel faint
- Significant changes in consciousness
It's understandable to feel anxious given your symptoms, but remember that you are taking proactive steps by consulting your doctor. This appointment will provide you with tailored medical insights and potentially necessary tests. If you feel overwhelmed before your appointment, don't hesitate to share your worries with someone you trust to ease your mind.

Seeking Insights on a New Medication Prescription
Recently, I visited a clinic as a new patient to initiate my healthcare journey. It had been a few years since my last check-up. I had previously been diagnosed with high blood pressure, for which lisinopril at 10 mg had been effective. After losing some weight, I managed to bring my blood pressure under control and subsequently stopped taking the medication. Life brought a series of stressful transitions, including a move, and I never resumed regular visits to my doctor. To keep track of my progress, I use a home monitor, which usually records my readings between 125/75 and 145/88. Given those fluctuations, I anticipated needing to return to blood pressure medication. I sought help from this clinic due to recent digestive troubles, which prompted a visit to urgent care. Following an evaluation there, the doctor suspected I might have Irritable Bowel Syndrome (IBS). However, when I visited the new clinic to re-establish care, I felt overwhelmed, especially since I was dealing with my illness and the pressure of meeting a new physician. Compounding my worries, I have a history of mild to moderate anxiety. During my initial check, my blood pressure was alarmingly high at 170/95, and a subsequent reading showed it at 155/90. This naturally raised concerns for both my doctor and myself; my heart rate was elevated as well, fluctuating between 100 and 115 right at that moment due to my anxiety and the stress from the high readings and medical responses. The medical assistant performed an EKG, and after reviewing the results, she pointed out a few irregularities that might indicate an enlarged heart. I couldn't recall all the details she shared, but she suggested that I consult a cardiologist as a precaution, which only added to my anxiety. She prescribed me metoprolol succinate ER at a dosage of 50 mg, and I have reservations about this treatment choice; I suspect my apprehension might be clouding my judgment. Is it standard practice to prescribe this medication to a new patient after just one appointment? My home blood pressure readings tend to be more favorable than those recorded at the office, and my heart rate generally stays between 60 and 80 when I’m at home, only increasing to about 90 to 110 when I’m out walking in the summer heat with my dog. Should I reach out to the clinic to better understand the reasoning behind this particular medication and dosage? I realize I may come off as lacking expertise when raising these questions, but I’m also a firm believer in advocating for my health. I tend to hesitate to ask questions when uncertain, and I fear not voicing concerns could be problematic. A physician friend of mine found the prescribed medication somewhat unusual for a first-time visit and felt the starting dosage was comparatively high for blood pressure treatment. He expressed interest in reviewing the EKG results, so I am in the process of obtaining those. Any feedback or suggestions would be immensely valued.
Seeking Guidance on Health Anxiety and Doctor's Response
Am I overreacting regarding my doctor's advice? At 28 years old and generally healthy, I've previously undergone surgery to remove cysts. Recently, however, I've been feeling anxious about a lump on my back that an ultrasound deemed inconclusive, yet not alarming enough for immediate concern. I was subsequently directed to have another ultrasound for a cyst, which the doctor confirmed is not a lipoma. I experience discomfort, particularly when certain postures put pressure on the surrounding muscles. Despite the medical assessments, I've found myself spiraling into thoughts of cancer, largely because this cyst is relatively deep, coupled with ongoing fatigue and issues with my wrist. It's possible I am just succumbing to stress rather than facing an actual health issue. The MRI I've been scheduled for isn't treated as urgent, and I've been told it could take around two months to get an appointment. When I inquired directly about the likelihood of cancer, my doctor assured me it was unlikely, and I've voiced my worries during our discussions. I'd like to know if this anticipated wait time is reasonable, as I find myself needing some reassurance. I'm on the brink of heading to the ER, but part of me thinks I may be overreacting. This intense health anxiety is new territory for me; I’ve never experienced it before until now.
Concerns About Sexual Side Effects from Pristiq
Hello everyone, my boyfriend, who is 22 years old, stands 6 feet tall and weighs 135 pounds, has been experiencing sexual side effects after starting a 50mg dose of Pristiq approximately two weeks ago. He’s struggling to achieve ejaculation. He has a follow-up appointment scheduled for next month, but it seems challenging to contact his doctor before that. We are wondering how long we should allow these side effects to persist before seeking a resolution. Should he consider arranging an earlier appointment? Additionally, he is currently prescribed 150mg of Wellbutrin and 50mg of Seroquel, having recently transitioned from Wellbutrin to Pristiq due to issues with weight loss, which is concerning since he is already quite slender. We are also curious about alternative treatments available for him, as he is battling depression and sleeplessness. In the past, he has tried several SSRIs, but they too resulted in sexual side effects that did not subside. Although Remeron was beneficial initially and helped him gain some weight—bringing him up to 145 pounds—it eventually made him quite restless after about a year of use. At the moment, his family doctor is managing his prescriptions while he awaits an appointment with a psychiatrist. Wellbutrin had been significantly helpful for his mood and sexual health, but it led to substantial weight loss, despite his efforts to increase his food intake. We are feeling a bit overwhelmed by this situation. Our goal is to find a medication that will not adversely affect his weight or lead to further sexual complications.
Understanding the Hazards of Dialysis
Greetings, I would like to share a bit about my mother. She is 63 years old and received a kidney transplant nine years ago, in August 2016, from a donor who had passed away. Recently, 41 days ago, she faced a health crisis that led to her hospitalization due to breathing difficulties and confusion. The diagnosis revealed a series of serious conditions, including pleural effusion, congestive heart failure, acute kidney injury, pneumonia, and a urinary tract infection. She was quickly transferred to the intensive care unit. After undergoing a thoracentesis and treatment with Lasix, her condition improved, allowing her to leave the ICU. On May 15, doctors restarted her dialysis in an effort to alleviate the fluid buildup in her body. However, on May 22, the nephrologist decided to remove the dialysis line and halt the procedure. This decision was contested by her pulmonologist, who expressed worries about the potential reaccumulation of fluid around her lungs. By June 14, her condition worsened as the fluid returned, necessitating her readmission to intensive care. On June 16, after a period of waiting, she was placed on dialysis once more, and another thoracentesis was performed by the intensivist. Despite sedation, she experienced a significant decrease in her respiratory rate, which eventually led to intubation. As of June 18, she remains on a ventilator. On the 15th, I reached out for clarification regarding the delay in resuming dialysis and learned from a nurse that they aim to maximize kidney function for as long as possible since dialysis can be debilitating, prioritizing the longevity of the transplanted kidney. There appears to be a conflict between the pulmonologist and the nephrologist regarding her treatment. I am beginning to feel that the nephrologist may have been negligent, placing the preservation of my mother’s kidney above her overall health and safety. I am not seeking legal advice concerning malpractice; rather, I would appreciate insights from anyone familiar with the standards of care in nephrology. Should the nephrologist have opted to continue dialysis sooner? My mother was on dialysis for nine years prior to her transplant, and I find myself overwhelmed with anger and concern during this difficult time.
Fear of Brain-Eating Amoeba
Greetings. I’m a 15-year-old who has been struggling with severe health anxiety. Last night, I went swimming in Lake Michigan with a friend, and now I’ve woken up with a headache. Although the water was quite chilly, I accidentally inhaled some through my nose, and ever since we departed from the beach, I’ve been in a state of panic. Should I be worried about this? I just want to savor my summer without the fear of serious illness. Any advice would be greatly appreciated.
