Diarrhea, Elevated Heart Rate, and Low Blood Pressure Concerns
A 28-year-old male, standing at 161 cm and weighing 60 kg, began experiencing symptoms yesterday morning around 6 a.m. Initially, he felt feverish with a temperature fluctuating between 36.8°C and 37.4°C. Shortly after, he started to have frequent bowel movements, estimating a total of approximately 7 to 8 occurrences from 6 a.m. yesterday to 6 a.m. today. Although there was no significant stomach pain, he experienced mild discomfort. According to the Bristol stool scale, his stools were categorized as type 6 and were brown in color. Additionally, he has observed a decline in his blood pressure, which typically sits around 130/85 mmHg at rest, with a heart rate of about 80 beats per minute. Since yesterday, he noted his resting heart rate fluctuating between 95 and 110 bpm. After taking a 6-hour nap this afternoon, his blood pressure read 117/78 mmHg with a heart rate of 90 bpm. Notably, he experienced a rapid increase in heart rate to 140 bpm within one minute of standing from a lying position. As of now, the individual reports no other symptoms such as faintness, though he did experience brief moments of dizziness when standing up yesterday. There are no signs of nausea, and his appetite remains intact. He is hydrating adequately with frequent urination intervals of about every 1.5 to 2 hours, producing light yellow urine. Could it be normal for blood pressure and heart rate to be influenced by the episodes of diarrhea?

Your symptoms of diarrhea along with an elevated heart rate and fluctuating blood pressure can indeed be related. Diarrhea can lead to dehydration, which might explain your cardiovascular changes, including the increased heart rate and lower blood pressure. Let’s break this down further.
Explanation
-
Diarrhea and Dehydration: Frequent bowel movements, especially if they are watery (like type 6 on the Bristol stool scale), can result in fluid loss. This can lead to dehydration, which in turn can cause your heart to pump faster (tachycardia) as your body tries to maintain adequate blood flow.
-
Blood Pressure and Heart Rate: Your resting heart rate increase (95 to 110 bpm) during this time may indicate your body is compensating for the lower blood volume due to the fluid loss. The brief moments of dizziness you noted when standing can also be a symptom of dehydration or orthostatic hypotension (a drop in blood pressure when changing positions).
Next Steps
-
Hydration: Prioritize rehydrating with fluids that contain electrolytes (like sports drinks or oral rehydration solutions). Aim to drink at least 2-3 liters of fluids throughout the day.
-
Monitor Symptoms: Keep track of your heart rate and any changes in your blood pressure or symptoms. Note any increases in dizziness or other concerning symptoms.
-
Diet Adjustments: While you maintain your appetite, try consuming easy-to-digest foods (like bananas, rice, applesauce, and toast – known as the BRAT diet) to help stabilize your bowel movements.
-
Rest: Ensure you are getting adequate rest to allow your body to recover. Avoid strenuous activities until symptoms improve.
-
Seek Help if Needed: If you experience worsening symptoms, such as persistent high heart rate, significant dizziness, fainting, severe abdominal pain, or bloody stools, it's important to seek medical attention promptly.
Take care of yourself and monitor your symptoms closely. If anything changes or if you have further questions, feel free to ask!

Struggling with Persistent Neck and Head Discomfort After Workouts – Seeking Guidance
Hello! I’m a 19-year-old female and have been dealing with unusual neck and head sensations that seem to linger. I would greatly value any advice or shared experiences. **Background:** - I maintain an active lifestyle, engaging in weight training four to five times weekly, plus running once or twice. - My workouts take place at Planet Fitness, focusing on muscle toning rather than heavy lifting. - My height is about 5’7” and I weigh approximately 126 lbs. - Although I do not have any severe health issues, I experience dizziness upon standing, occasionally leading to fainting spells. My physician indicates my blood pressure is normal, but I suspect it might be lower than what’s ideal. - I should mention that I take Adderall and Sertraline for managing ADHD and anxiety symptoms. - I also struggle with sinus issues due to narrow nasal passages, making it harder to clear mucus during colder seasons and increasing my susceptibility to infections. **Medical Evaluations:** - Blood tests returned normal results. - A neurologist examined me and found no neurological impairments. - An MRI revealed no abnormalities. **Onset of Symptoms:** The trouble began in early May, particularly while performing hip thrusts. I noticed a peculiar sensation in my sternocleidomastoid (SCM) muscle, feeling as if it was catching near a lymph node below my jaw, particularly when my chin was tucked and my head unsupported. Though there was no pain, it was disconcerting. Despite this, I continued with my workouts. Since then, the lymph node in that area has remained tender to the touch. Typically, I conclude my workouts with abdominal exercises, which include: - Weighted decline sit-ups - Hanging leg raises - Weighted toe reaches - Using the ab slide at Planet Fitness After completing decline sit-ups one day, I stood up and experienced lightheadedness along with fullness in my ears, as if they needed to pop. I thought nothing of it. Later that evening, while washing my hair, tilting my head back intensified the soreness in my head. When returning to an upright position, the discomfort escalated further — this sensation mirrored the angle from the decline abs. Keeping my mouth open worsened it too. In the following days, sipping liquids induced soreness in my neck, which felt strained and overworked. When I began to see a bit of recovery, I returned to the gym, and although my workout seemed typical that Saturday, I became dizzy again post-session, had fullness in my ears, and later experienced an extremely unusual headache: - It initiated at the lower right section of my head. - The pain radiated upward and was predominately isolated to one side. - It felt dull and throbbing, with a pattern of emergence and retreat. - This headache persisted for five days. - Even as it subsided, my head maintained a peculiar sensation, as if under pressure. **Current State:** Since that episode, the discomfort has fluctuated. There was one particularly tough week marked by: - Severe, migraine-like pain behind my right eye. - Intense tiredness, feeling as though my brain was completely exhausted. - No amount of rest seemed sufficient. I took a substantial five-day break from exercise and changed contact lenses, which brought some relief to the eye discomfort. However, upon attempting light abdominal workouts again, I found my neck felt tight and activated, regardless of how cautious I tried to be. Additionally, there was notable pressure at the base of my skull on the right side, especially when I turned my head. - The more intense pain has subsided, but I remain anxious about its return. - I’ve refrained from any neck-straining movements, but I miss the freedom of exercising without fear. - Occasionally, I wake up with a sore head and overall tightness. - This situation has been disheartening as exercise typically brings me happiness. **Seeking Opinions:** Has anyone else encountered peculiar pressure headaches, neck or SCM strain, or eye discomfort following ab exercises or hip thrusts? Could this issue be cervicogenic, nerve-related, or muscular in origin? I welcome any insights, similar experiences, or recommendations for specialists to consult. My hope is to recover and confidently resume my training without this ongoing anxiety. Any thoughts would be greatly appreciated!
Safety Considerations for Hiking with Possible Chiari Malformation
Hello, I’m a 25-year-old transgender woman residing in Colombia. Some years back, I was told I have Chiari malformation type II, though I now question whether it might actually be type I, as I don't exhibit symptoms like spina bifida or hydrocephalus. Unfortunately, I misplaced the documentation from that diagnosis. This was around the time I was managing gallbladder problems, culminating in its removal. Since losing my job, I’ve had no healthcare follow-up. Additionally, I have Gilbert Syndrome and do not consume alcohol. Recently, I have encountered several concerning symptoms: * Issues with coordination, which sometimes manifests as a delay between the command from my brain and the response from my muscles. Interestingly, I can still type at about 50 words per minute without difficulty. * A prevalent sense of "brain fog" that resembles what is often termed executive dysfunction; I suspect this might be exacerbated by anxiety. * My anxiety has increased, along with episodes of panic. I also have a confirmed diagnosis of autism and hyperthyroidism. Despite these challenges, I have enjoyed hiking Monserrate, a trail in Bogotá that ascends from approximately 2,500 meters to about 3,400 meters, gaining around 900 meters in altitude. I find this activity rejuvenating for my mental well-being; however, I am now anxious that it might be straining my spine or brainstem, potentially worsening my condition. Currently, I lack access to medical professionals but am actively seeking employment so that I can obtain insurance and pursue further evaluations. Hence, I would like to know: **Is it advisable for me to continue hiking at high elevations considering the possibility of having an undiagnosed Chiari malformation, or should I refrain from these activities until I can secure appropriate imaging?** I understand that no one here can provide a diagnosis, but I would greatly appreciate any insights regarding the risks associated with engaging in such physical activities while potentially dealing with Chiari malformation. Thank you for your assistance.
When Should You Return to the Doctor?
A 20-year-old woman, standing at 5 feet 8 inches and weighing 150 pounds, who does not smoke, is currently on several medications including metoprolol, Allegra, a birth control pill, amitriptyline, zofran, and ketamine troches. She has a history of asthma, allergies, POTS, prior sinus surgery, along with other unrelated health issues. Recently, she returned from a rainy and humid trip to New York, only to find herself back home in the arid conditions of Idaho, which exacerbated her allergies and asthma significantly. Over the course of several days, she experienced relentless coughing. Last Tuesday, she sought help at urgent care due to shortness of breath. Tests ruled out any other illness, and she was prescribed prednisone for a brief period alongside a new inhaler, with instructions to return if any infection symptoms emerged. By Thursday, she woke up with severe ear pain and experienced hearing loss. Upon returning to urgent care, she was diagnosed with an ear infection and started on amoxicillin. After completing the steroid treatment and 11 doses of antibiotics, she hasn’t seen substantial improvement. Although the coughing has decreased, it remains significantly above her normal level, accompanied by excessive mucus that complicates her breathing. The ear infection has worsened, and pain has extended to her sinuses. Now, she wonders whether she should revisit urgent care, consult an ENT specialist, or complete her course of antibiotics first. Despite experiencing various infections and health challenges before, she has never encountered anything quite like this. Additionally, her POTS condition has intensified due to the coughing, resulting in considerable chest discomfort, although imaging conducted at urgent care yielded normal results. Moreover, it’s worth mentioning that her profession involves music, and this infection has severely impacted her ability to perform. Should she pursue further medical assistance?
Understanding Migraines: A Deeper Concern?
I am a 29-year-old woman who has suffered from migraines since I was a child, around 2 or 3 years old. Throughout the years, I have struggled to identify any specific cause or triggers for these headaches. My healthcare providers have never seemed alarmed by my condition, and none have recommended diagnostic imaging or further testing. I have explored numerous remedies but eventually resigned myself to managing these headaches as a regular aspect of my life. Recently, I have begun to experience additional troubling symptoms, including episodes of vertigo, increased clumsiness (which my friends have noticed), and intense nausea, all while the frequency of my migraines has surged. A few weeks ago, I experienced what I suspect to be a hemiplegic migraine, which led me to mistakenly believe I was having a stroke. Despite these new developments, my physician seems unfazed. Given this context, I find myself wondering if I should advocate for imaging or other tests to gain a clearer understanding of my situation, or am I perhaps overreacting? I appreciate any guidance or insight you can share!
Worried About Throat Bumps Turning White After GP Visit – Should I Return?
Hi everyone, I wanted to share my concerns about my throat. I started experiencing discomfort yesterday, and upon checking, I discovered some red bumps at the back of my throat. I quickly sent a picture to my general practitioner, who indicated that it appeared to be retention cysts caused by blocked mucus glands and advised me to keep an eye on it for a few days. Currently, my symptoms include a slight cough and a very mild sore throat. However, after inspecting my throat again today, I noticed that the bumps seem to be developing a white hue. I’m uncertain if this is due to the different lighting conditions, as the first photo was taken at night while the second was during the daytime. Could someone please help me assess the situation? Is it reasonable for me to continue monitoring my condition for the next few days since I don’t have any additional symptoms? For context, I have a medical history that includes anxiety and reflux issues. Thank you! 28-year-old male
