Are Sugar-Free Energy Drinks Linked to Low eGFR and Elevated Creatinine Levels?
My husband, who is 31 years old, weighs 240 pounds and stands at 5'11", has struggled with anxiety and depression in the past. Aside from that, he has no notable health complications and does not take any medications or supplements. He works night shifts and regularly consumes sugar-free energy drinks, particularly Monster. Recently, he noticed some unusual changes in his urine—namely, a strange odor and a darker, frothy appearance. Given that his father passed away due to liver failure, my husband is understandably concerned. His father had a history of Hepatitis C, which I believe was treated, yet he was also an alcoholic, a heavy smoker, and had untreated hypertension. I've attempted to reassure my husband that his health issues are not inherited. During a recent checkup, it was found that his urine contained a small amount of bilirubin and protein levels were at 30. Here are his results from yesterday: - **eGFR:** 66 mL/min/1.73 m² (Low; normal reference is 90) - **Creatinine:** 1.45 mg/dL (High; normal range is 0.6-1.1) - **AST:** 47 unit/L (High; normal range is 15-37) Last month, his eGFR was within the normal range, but his alkaline phosphate was slightly elevated at 129, and his ALT was borderline high as well. The rest of his results were acceptable. Next month, he plans to switch to daytime work, which I hope will reduce his reliance on energy drinks. Nonetheless, I'm anxious that potential damage might have already occurred. As far as I know, he typically consumes just one drink per night, although it’s possible it could be two. Thank you for your input.

It’s understandable that you and your husband are feeling worried about his recent lab results and changes in his health. Based on the information provided, we can address his elevated creatinine levels, eGFR, and overall health implications related to energy drink consumption.
Main Points:
- Current Findings: Your husband has elevated creatinine and AST levels, low eGFR, and changes in urine appearance, which could indicate kidney stress or potential liver issues.
- Energy Drink Impact: Sugar-free energy drinks, particularly those high in caffeine and artificial additives, can sometimes contribute to kidney and liver stress, especially with excessive consumption.
Explanation:
The eGFR (estimated Glomerular Filtration Rate) gives insight into kidney function, with normal values typically above 90 mL/min. His current reading of 66 is concerning and suggests reduced kidney function. High creatinine levels further support potential kidney stress. Additionally, the presence of bilirubin and protein in the urine can indicate problems either with the kidneys or the liver.
Given your husband’s family history and the recent changes in his health, it’s essential to take these findings seriously. The fact that he plans to reduce his energy drink consumption as he transitions to daytime work is a positive step.
Next Steps:
-
Limit Energy Drinks: Encourage your husband to significantly reduce or eliminate the consumption of sugar-free energy drinks. This could help alleviate any additional stress on his kidneys and liver.
-
Hydrate Fluently: Ensure he drinks plenty of water throughout the day. Proper hydration can support kidney function and help dilute urine, potentially improving its appearance.
-
Monitor Symptoms: Keep a close eye on any further changes in urine color, odor, or clarity. Note any other symptoms like fatigue, swelling, or changes in appetite.
-
Maintain a Balanced Diet: Focus on a nutrient-rich diet that includes plenty of fruits, vegetables, lean proteins, and whole grains while reducing processed foods and high-sugar items.
-
Follow-Up Testing: Plan to have follow-up lab tests to monitor kidney function (eGFR, creatinine) and liver enzymes (AST, ALT) as recommended by a healthcare provider.
-
Health Routine: Encourage him to adopt a healthier lifestyle that includes regular exercise and stress-management techniques to support his overall well-being, especially considering his past struggles with anxiety and depression.
If any concerning symptoms arise, such as severe fatigue, nausea, vomiting, or significant changes in urine output, it would be important to seek medical attention sooner rather than later.
Remember, while family history can be alarming, many lifestyle adjustments can make a significant difference in health outcomes. Your support in following these steps can greatly help him feel better and manage his health more effectively.

A Mysterious Illness That Resembles Strep Throat
As an 18-year-old college student, standing at 5'4" and weighing 140 pounds, I maintain an active lifestyle. I do not smoke or have any preexisting health issues, aside from the vitamins and supplements I take daily. Approximately five days ago, I began to feel unusually fatigued and achy. Within just a day, my symptoms escalated to include a high fever reaching between 101°F and 102°F that ibuprofen couldn’t seem to alleviate. I experienced extreme tiredness that kept me bedridden all day, along with a persistent headache and intense throat pain, which was compounded by swollen lymph nodes and the familiar white patches often associated with strep throat. Having dealt with strep throat before, I recognized a need for antibiotics. Two days into feeling unwell, I visited an urgent care facility for an assessment and received a rapid strep test, which unfortunately came back negative. I recalled a previous incident where my rapid strep test also indicated a false negative, only for the culture sent for further testing to confirm the presence of strep bacteria. Given my symptoms and the findings from the examination, the healthcare provider prescribed Cefdinir, as I am allergic to amoxicillin, despite the negative rapid test results. The antibiotics proved effective, and I felt nearly back to normal, leading me to believe that my culture results would also come back positive for strep, suggesting a recurrence of my previous infection. However, I received the culture results yesterday, and to my surprise, they came back negative for strep. While I lack medical expertise, I’ve been led to believe that false negatives in cultures are exceedingly rare. Now, I find myself puzzled about what kind of bacterial infection I might have had if it wasn’t strep. Any insights or information regarding my situation would be greatly appreciated. Thank you!
Bleeding Concerns with IUD and Yeast Infection Treatment
I’m a 20-year-old female, standing at 5’4” and weighing 155 pounds. Hello everyone! Approximately three weeks ago, I had the Kyleena IUD placed, and everything felt fine afterward—I can still feel the strings. I noticed some mild spotting that was brown for about a week, followed by my menstrual period, then continued with light spotting. Recently, I suspect that I might have developed a yeast infection, which I am currently addressing using Monistat 7. I applied the first dose yesterday. To clarify, I am certain that I am not dealing with a sexually transmitted infection. However, I’ve observed an increase in bleeding, significantly more than what I’ve experienced before. The blood appears to be light red, and I would compare the amount to the lightest day of my period. I could comfortably go an entire day without needing to change my pad, though I still do it for hygiene reasons. Is this a common occurrence? Most of the bleeding took place this morning after I woke up, coinciding with the Monistat cream leaving my body. Under what circumstances should I seek medical advice regarding this issue instead of waiting to see how the treatment progresses?
Understanding Recurrent Symptoms: Are They Histamine-Related?
Hello, health professionals, I am seeking your expertise regarding a variety of symptoms I have been experiencing intermittently over the years. While they appear linked, I'm having difficulty pinpointing their root cause. **Personal Summary:** - 27 years old, Female - Non-smoker (formerly vaped for about eight years, cessation initiated two years ago) - No diagnosed autoimmune conditions - Background of anxiety (which might exacerbate some symptoms, though it doesn't account for all) - Currently taking Flonase and a multivitamin **Skin Reactions:** - I've dealt with recurring itchy rashes and hive-like bumps since childhood. They manifest suddenly and usually resolve without intervention. - These rashes are often itchy, can be raised, and tend to appear sporadically without identifiable triggers. - Antihistamines provide consistent relief, leading me to suspect a role of histamines in these eruptions. - These episodes do not align with typical contact allergies or classic food allergies. - They can happen multiple times daily, and I've often dismissed them as merely anxiety-related rashes. - Sometimes the itching precedes the visible rash, while other instances present with a red, inflamed area that stirs inquiries about my well-being from others. **Foot Discomfort:** - Over the last few years, I’ve encountered severe itching on the soles of my feet. - These episodes typically include small pale or white spots with redness surrounding them, occasionally featuring a red center. - Itching intensity can be overwhelming, yet these lesions usually arise suddenly, - They frequently improve upon avoiding scratching and may resolve within a range of 30 minutes to two days. - The first episode was triggered after swimming in a freshwater lake, though I’ve also experienced it while wearing specific footwear like Crocs or boots, but not consistently. - Certain events coincide with my typical skin rash, hinting at a potential systemic condition rather than merely a localized issue. - The symptoms do not mirror those of warts, ringworm, or fungal infections. **Ear and Sinus Issues:** - Itchy ears have been a recurring issue for the past few years; I initially attributed it to overly aggressive cleaning with cotton swabs, which I realize is harmful. - I have a history of chronic sinus problems, including post-nasal drip and regular ear infections. - The inflammation appears to flare up sporadically rather than constantly. - Recently, I experienced a painful ear issue that began with what I thought was a pimple. The next day, my ear was swollen. After visiting a clinic, I was diagnosed with a double ear and sinus infection, treated with antibiotics. My pain persisted, leading to a follow-up with my primary care physician, who prescribed Flonase and noted ongoing nasal inflammation. Missing doses led to increased ear discomfort, prompting me to take Flonase more regularly. Unfortunately, a recent flare of swelling and discomfort in my ear led me to consider consulting an ENT specialist. **Gastrointestinal Symptoms:** - I was diagnosed with gastritis through an upper endoscopy procedure. - Testing for H. pylori returned negative. - I've since developed food sensitivities and gastrointestinal discomfort not previously experienced. - I saw significant improvement after removing gluten and dairy from my diet, with tests for celiac disease yielding negative results. - Symptoms tend to flare up in response to stress or specific food intake rather than being a constant presence. **Additional Context:** - A history of childhood asthma (now occurs infrequently) - Sensitivity to heat - Past instances of feeling lightheaded, resembling vasovagal symptoms, alongside vertigo - Symptoms across various systems often flare together, but not in every instance - While my anxiety can intensify symptoms, both antihistamines and diet modifications have had notable positive effects **My Inquiry:** While I don’t wish to self-diagnose, I'm curious if my range of symptoms might suggest: - Histamine intolerance - Mast-cell overactivity (not necessarily MCAS, but an increased reaction) - Physical or contact urticaria I'm primarily seeking: - Recommendations for a suitable specialist - Insight on whether this symptom pattern fits a recognized mechanism - A clearer understanding of what warning signs to be concerned about **Summary:** I contend with a long-standing pattern of episodic itchy rashes and hives, significant but transient foot itching along with bumps, persistent ear irritation coupled with sinus problems, and gastritis accompanied by food sensitivities that improved on an elimination diet. Antihistamines aid multiple symptoms. Could this suggest underlying histamine-related issues manifesting across multiple systems rather than in isolation?
Seeking Guidance on Persistent Chest Discomfort After Extensive Testing
I'm a 43-year-old male, standing at 5'11" and weighing 180 pounds. My journey began around March to April of 2025 when, despite regularly hitting the gym four times a week, I was struck by severe chest pain along with frequent belching and a tight feeling in my diaphragm. At times, the pain became so intense that I feared it might be a heart attack. **Medical History:** In May 2019, I received a diagnosis of **PVS** and have since been under the care of a cardiac electrophysiologist. Upon experiencing these new symptoms, I consulted my EP, who conducted an EKG right then and set me up with a 7-day heart monitor. The results showed no irregularities. Subsequently, I was directed to a cardiologist, who carried out both a **stress test** and an **echocardiogram**, both of which yielded normal findings. Afterward, I returned to my primary care physician, who speculated that my gallbladder might be involved. An **ultrasound** was performed but revealed no issues. I then requested a **chest X-ray**, which also came back normal. My PCP then considered the possibility of a **hiatal hernia** and referred me to a gastroenterologist; unfortunately, that appointment took almost **five months** to materialize. In the meantime, my symptoms persisted, prompting me to cease weightlifting and switch my focus to **cardio and running**. Surprisingly, these activities didn’t exacerbate my symptoms, though the chest pain remained constant. When I finally saw the gastroenterologist, they suggested an **upper endoscopy**, which took another roughly three months to arrange. During this procedure, I was diagnosed with **Eosinophilic Esophagitis (EOE)**, a condition I had not previously experienced. The doctors also placed a pH monitoring device for acid reflux assessment, which indicated **no unusual acid exposure**. Following this, I began a treatment plan that included a swallowed steroid inhaler and an increased dosage of **omeprazole**. Sixty days later, I underwent another endoscopy, which showed that the EOE had largely resolved, with minimal residual symptoms. Unfortunately, my chest discomfort persisted without any improvement. It has now been about **a year** since these issues emerged, and I still have not found substantial relief. A recent chest MRI completed at a dedicated imaging center revealed no abnormalities. I entertained the idea of **costochondritis**, but again, the MRI did not support that hypothesis. The only minor relief I find comes from consciously pulling my shoulders back and expanding my chest. I continue to experience discomfort around my **diaphragm** and tenderness in the area of the **xiphoid process**. My PCP prescribed a steroid pack, which was somewhat beneficial for the pain but failed to alleviate the pressure or constant discomfort. At this juncture, I feel quite lost and uncertain about my next steps. I would greatly appreciate any insights or experiences from others who have faced similar issues. Additionally, if there are any physicians here willing to offer advice, I am open to traveling to find the answers or relief I'm desperately seeking.
Understanding Mild Uncomplicated Diverticular Disease
I am a 29-year-old female, standing at 5'7" and weighing 130 pounds. Recently, a CT scan revealed that I have mild diverticulitis. About a week ago, I experienced significant discomfort, particularly in the pelvic region, along with pain in my right leg and hip, and some mild discomfort on the left side. After undergoing a CT scan, which confirmed the presence of mild diverticular disease, I was surprised that no one from my medical team provided any follow-up or acknowledged the condition. My blood tests returned normal results, and I was discharged without further information. While the pain subsided after about three days, it has unfortunately reappeared four days later. Is this something I should be worried about? What does this mean for me? I had a colonoscopy around 11 months ago, which indicated no issues.
