Experiencing Heart Palpitations Following Food Poisoning
Age: 28 | Height: 6'0" | Weight: 84 kg A couple of weeks ago, I suffered from food poisoning linked to some spoiled fish. Although I have recovered from the primary symptoms—initially some vomiting and predominantly diarrhea—I've encountered a new issue. I’ve started experiencing what I believe to be heart palpitations, which feel like quick, sharp discomforts on the left side of my chest, often accompanied by a sensation of a forceful heartbeat. These episodes aren’t extremely painful; they’re more of an irritating sensation. Interestingly, they tend to arise when I am standing, predominantly after meals. However, there are exceptions; for example, if I get up from resting to use the restroom, I might feel one of these sharp sensations. On days when I’m on my feet, I notice this occurs every 20 to 30 minutes, though sometimes the intervals are shorter or longer. Just yesterday, after having coffee, I took a two-hour walk without experiencing any palpitations at all. Importantly, I’m not experiencing any additional symptoms alongside this issue.

It sounds like you're experiencing heart palpitations that began after a bout of food poisoning, and this is understandably concerning. This reaction could be due to several factors, including post-infectious irritation, dehydration, or even anxiety related to your previous illness. It's reassuring that you're not experiencing severe symptoms, but it’s still important to take steps to address these palpitations.
Explanation
Heart palpitations can occur for a variety of reasons, including stress, caffeine intake, dehydration, or changes in your body’s electrolyte levels, especially following an illness that involved significant gastrointestinal distress. The sharp sensations on the left side of the chest that occur while standing or after meals could be related to your body adjusting after the infection, but it's vital to pay attention to the patterns and frequency.
Next Steps
-
Monitor Hydration: Make sure you are drinking plenty of fluids to stay hydrated, especially after experiencing diarrhea. Electrolyte drinks can be helpful, as they restore the minerals your body may have lost.
-
Dietary Considerations: Pay attention to your meals. After food poisoning, introduce light, easy-to-digest foods gradually. Avoid caffeine and heavy meals to see if this reduces palpitations.
-
Rest and Stress Management: Practice relaxation techniques such as deep breathing or meditation. Stress and anxiety can exacerbate palpitations, especially after a stressful experience like food poisoning.
-
Activity Level: Gradually increase your activity level, and listen to your body. Since you noticed palpitations seem to vary based on your activity, try standing or walking at a pace that feels comfortable and see if that improves your symptoms.
-
Keep a Symptom Diary: Document the timing, frequency, and circumstances surrounding your palpitations. Note your meal timings, any stress factors, and hydration levels. This information can help identify patterns and triggers.
If symptoms persist or worsen, or if you start experiencing additional symptoms such as shortness of breath, dizziness, or chest pain, consider seeking professional medical advice to rule out any serious underlying issues. Your comfort and well-being are important, so feel free to keep track of these experiences and take care of yourself!

Suspecting a Fracture Despite Medical Opinions
I'm a 16-year-old girl, and back in January, I had an accident while skiing. At the time, the emergency room doctors mentioned they might have detected a fracture in my tibia. However, I was advised to wait for a few weeks until I could get an MRI to confirm the diagnosis. When the MRI results came in, they showed no signs of a fracture, but I can’t shake the feeling that what I see on the MRI resembles a fracture. I'm reaching out for your thoughts on this matter.

Are Herbal Teas Supported by Science?
As a 20-year-old male, I’ve delved deeply into the purported health advantages of herbal teas, particularly in areas like anxiety and hypertension. However, I find that scientific studies predominantly fail to substantiate many of these assertions, with the exception of the antioxidant qualities that some teas may possess. When research does exist, it often appears to be inconclusive or only somewhat convincing. Perhaps I haven’t come across everything—does anyone have additional insights regarding these claims? Are they backed by solid evidence?
Concerns Regarding Persistent Epithelial Cells and RBCs in Urine Post-UTI Treatment
At 33 years of age and married, I experienced concerning symptoms following a week of vigorous intimacy with my husband. Shortly thereafter, I began noticing signs consistent with a urinary tract infection (UTI), including blood in my urine and a burning sensation while urinating, although I did not have a fever. Concerned, I consulted a physician and underwent my first urine analysis, revealing: - Leukocytes: 70 - RBC: 8-10 - WBC: Count so high that it was unquantifiable - Epithelial Cells: Moderate - All other parameters were either normal or negative. The doctor prescribed a week-long course of antibiotics. A few days into the treatment, I started to feel much better, with no pain and clear urine. Once I completed the medication, we didn’t give it much thought. However, after a month, we decided to have another urine test to confirm that everything had returned to normal. Here are the results from that latest test: - Leukocytes: Negative - RBC: 0-2 - WBC: 2-4 - Epithelial Cells: Moderate - Bacteria: Rare All other readings, such as glucose and ketones, were within normal limits. Despite the RBC count being between 2-4 and the presence of moderate epithelial cells, I haven’t experienced any more symptoms since the initial days. This lingering issue has me feeling a bit anxious. I would appreciate any advice or insights on what this all means.
