Hydrate her oral, IV: If indeed she's not drinking enough fluid, then you're right to keep her well hydrated and in a cool place. If she's not able to drink because of the vomiting then, she will need IV fluid replacements. For now, it's safe to assume its heat exhaustion but if symptoms recur under a different setting, she needs to see her physician. ...Read more

Could potassium level 3.5 be simple cause for my irregular heart beat, muscle cramps, exhaustion? Blood labs, chest xray, echo all read normal.

Could potassium level 3.5 be simple cause for my irregular heart beat, muscle cramps, exhaustion? Blood labs, chest xray, echo all read normal.

Potassium of 3.5: Although your potassium (k) of 3.5 meq/l is low, it is normal by lab standards. You should also have your doctor check your magnesium (m) level. A low m level can cause a low k, which cannot be corrected until the m level is normal as well. If both your k and m are not low on another blood test, you need to see a cardiologist to determine the cause of your cardiac problem. Good luck. ...Read more

Anxiety or stress can cause shortness of breath, dizziness or fatigue, sensation of failure of heart beats, or heart accelerated?

Anxiety or stress can cause shortness of breath, dizziness or fatigue, sensation of failure of heart beats, or heart accelerated?

Yes: Anxiety and panic attacks can cause all of these symptoms. However, it's still important to get an overall health evaluation from your physician to make sure all is well. The symptoms are not imaginary, but would not usually be accompanied by ekg abnormality besides tachycardia. Though it can feel like heart attack, anxiety would not produce lab evidence of heart damage (as heart attack does). ...Read more

I'm taking Maxzide (hydrocholorthiazide and triamterene) it's making me feel horrible. Out of breath fast heart beat fatigue and my BP is high 150/100. Can this cause this?

Electrolyte changes?: You might need to modify modification regimen. In addition, it is importnat to check electrolyte abnormalities. Speak with your physicians. It is important to know when you started takin Maxzide (hydrocholorthiazide and triamterene) and any other changes to medications. In my opinion, I would like to see what a bmp looked like to make sure you didn't have low sodium or other changes that could expalin this.
Hope you feel better Cheers ...Read more

I am heat sensitive and have been for years, it makes my heart beat fast and makes me feel tired and panicky, thyroid normal am 37, low bp?

Sweaty?: If your heat sensitive, tired with low bp, consider dehydration. Two major causes: sweating and not drinking enough? (if you have other fluid losses like diarrhea, vomiting, or bleeding, they would also contribute to your symptoms). Panicky does not fit- you may have two distinct issues. Uncontrolled diabetes, the rare entity, diabetes insipidus, and some drugs could contribute. ...Read more

If you take drugs (MJ) or smoke, drink alcohol or are obese or inactive, you will be negatively effected and may develop symptoms as you've described. ...Read more

Nothing: If you haven't had the echo, then the diagnosis of mvp has not been established. Even if you do have it, mvp does not cause these symptoms. Doctors blame all kinds of things on mvp but they are not related. There is no treatment required for mvp and none that is helpful.

Vocal cord dysfunction vs. Idiopathic environmental intolerance: Could be worthwhile considering vocal cord dysfunction (paradoxical vocal fold movement) as a contributing factor. This condition is often acutely exacerbated by strong scents/odors. More common in females and tends to affect patients with a history of high anxiety. Might be worthwhile getting PFTs and having a laryngoscope performed. Idiopathic environmental intolerance is another consideration but this is a diagnosis of exclusion. There are a number of filters and personal wearable devices that can help the patient deal with exposures in her environment. ...Read more
