Understanding Potential Causes for Low Phosphorus and Potassium Levels
Profile: 37 years old, 5'2", 110 pounds. Last summer, I faced a critical health situation leading to hospitalization due to severe weakness, which made walking and standing quite challenging, along with a rapid heartbeat and high blood pressure. I also experienced shortness of breath, widespread pain, hot flashes, excessive sweating, tingling sensations, swollen lymph nodes, and low-grade fevers. After undergoing an extensive medical evaluation, I was diagnosed with POTS, but the origins of some other symptoms remained undetermined. There were instances when my heart rate unexpectedly rose to the 180s, accompanied by several distressing symptoms, including some occurrences of supraventricular tachycardia (SVT). Fortunately, I was discharged after beginning a treatment regimen with metoprolol, which has significantly improved my condition. During the initial episodes of my accelerated heartbeat, my electrolyte levels were assessed, revealing a notably low phosphorus level of 1.2. Additionally, during my hospital stay, my potassium levels were consistently low, falling between 3.3 and 3.4. Tests on my urine indicated the presence of ketones. Although my dietary intake had slightly decreased, I was still consuming food, and a thorough nutritional assessment showed no deficiencies in essential nutrients, including vitamins and iron, nor indications of anemia. What might have contributed to these abnormal lab results? Is there a lingering concern regarding the possibility of low phosphorus levels in my future? The hospital addressed this issue, but my phosphorus levels have not been retested since discharge.

Main Points: Low levels of phosphorus and potassium can stem from various causes, particularly following significant health issues. Monitoring these levels is crucial, and there are actionable steps you can take to potentially improve your situation.
Explanation: Phosphorus and potassium are essential electrolytes that play important roles in muscle function, nerve signaling, and overall cell health. Low levels can result from multiple factors, particularly after a serious health event like hospitalization. Potential causes include:
- Inadequate dietary intake: Even if overall nutrients seem adequate, specific deficiencies can happen.
- Medication effects: Some medications, like diuretics, can cause electrolyte imbalances.
- Hormonal factors: Conditions affecting adrenal or kidney function can influence electrolyte levels.
- Fluid shifts: Significant illness or electrolyte imbalances may lead to shifts in body fluids that impact these levels.
- Conditions like POTS (Postural Orthostatic Tachycardia Syndrome): This condition can influence how your body regulates blood and fluids, impacting electrolyte levels.
As for lingering concerns regarding low phosphorus, while intermittent issues can occur, consistent monitoring and management can help prevent future imbalances.
Next Steps:
-
Dietary Review: Focus on foods rich in phosphorus (like fish, meat, nuts, and legumes) and potassium (found in bananas, oranges, potatoes, and leafy greens). Tracking your daily intake can help ensure you're getting enough.
-
Hydration: Maintaining proper hydration can assist in electrolyte balance. Consider discussing an electrolyte-rich drink with your healthcare provider.
-
Laboratory Monitoring: Request follow-up tests for phosphorus and potassium levels with your healthcare professional. Regular monitoring is essential given your previous lows.
-
Meditation & Relaxation Techniques: Given your history of POTS and associated symptoms, practice stress-reducing techniques, as stress can exacerbate your condition.
-
Educate & Empower: Learn more about your condition and possible dietary modifications. Consider speaking with a nutritionist if needed.
By taking these steps, you can better manage your health and address any potential future issues with phosphorus and potassium levels. If you have concerns or notice any new symptoms, don’t hesitate to reach out for further support.

24M | Unexplained Fainting Incident
**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?
Healing Progress Post-GBS: Toe Concerns
I am a 28-year-old male, measuring 5 feet 10 inches and weighing 131 pounds. My current medications include Fomadatine and Zyrtec, prescribed due to my ongoing battle with Chronic Gastritis and SIBO. I maintain a healthy lifestyle, abstaining from both smoking and alcohol. My health concern revolves around the toe adjacent to my pinky toe on my left foot, as well as my pinky toe on the right foot. Since August of last year, I have been on the mend from Guillain Barre Syndrome. Recently, I've noticed that at night, the skin on my feet tends to turn a reddish pink, although this usually improves after I walk around. However, two of my toes have remained red, with one appearing slightly swollen. Generally, my pinky toes are quite thick, but the condition of my left foot's toe is worrisome for me. It seems that I'm unable to upload an image to illustrate my issue.
Challenges with Appetite and Discomfort While Eating — Difficulty in Gaining Weight
As an 18-year-old male, I find that I become satisfied after consuming rather minimal amounts of food. This situation presents a considerable challenge, particularly since I only need to have a standard breakfast, lunch, or dinner to feel completely satiated for the remainder of the day. My goal of increasing my weight has made this issue even more complicated. When I limit myself to one meal per day, I often face weight loss or an uncomfortable sensation of fullness that leaves me feeling sluggish. Opting for two meals makes me feel excessively bloated, distracting me from my daily responsibilities. Moreover, I suffer from an unusual issue with my throat, where almost any food I consume causes discomfort, as detailed in the list below. I have contemplated focusing on having just lunch while continuing my weightlifting regimen to maintain my current weight and gradually build muscle. What advice could you offer? Could there be an underlying cause for these symptoms? Lastly, would it be wise for me to consult a healthcare professional? Foods That Cause Discomfort: Bread, flour, pizza, fruits, sugary or starchy items, seed oils, chips, and essentially everything else. Foods That Are Tolerable: Rice, salads, chicken, fish, and vegetables. Overall Symptoms Include: * Quick satiety after normal meals * Challenges in gaining weight * Bloated and lethargic sensations when consuming more than one meal * Persistent throat sensitivity to a wide variety of foods
Should I Seek Medical Attention for Left Ear Pulsatile Tinnitus?
A 31-year-old woman reports an ongoing issue with pulsatile tinnitus, which she is currently experiencing solely in her left ear. Although she's noticed this condition intermittently before, she hadn’t paid it much mind due to the absence of pain. Recently, however, her curiosity piqued her interest in researching the condition, where she stumbled upon information suggesting it could be serious. Usually, she avoids searching online for health worries, but now she is contemplating whether a visit to the doctor might be warranted. Can anyone advise on the need for a medical evaluation in this case?
Unusual Heart Sensation
I’m an 18-year-old, weighing 50 kilograms and standing at 170 centimeters (and yes, I’m aware that I’m quite slender). For the past couple of years, I’ve developed a habit of smoking about half a pack of cigarettes each day. So, the other day I was lying on my left side, relaxing, when I stumbled upon an unusual sensation. It felt as though my heart was pulsating so intensely that it was almost outside my body. Out of curiosity, I pressed a bit on the area and was instantly hit with a rush; my head started to tingle, my vision momentarily blurred, and it felt as though my heart dropped. It was as if my entire system had malfunctioned. Just for context, I’ve experienced something similar before after a ketamine overdose, and it persisted for about a month afterward, occurring occasionally while trying to sleep or during random moments in bed. This current episode has me quite anxious, especially since it hasn’t happened in a while, but this time felt particularly alarming.
