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.

Understanding My Neck Ultrasound Results
I'm a 30-year-old female, weighing 133 pounds and standing at 5 feet 7 inches. I lead a healthy lifestyle, without any alcohol or tobacco use. This morning, I visited urgent care due to a firm lump beneath my chin that feels immovable and solid. My doctor recommended an ultrasound, and I received the results, which I’ll be discussing with an ENT specialist next Thursday, along with my primary care physician on Wednesday. **Patient Background**: Notable lump thickness in the area below the chin. **Procedure**: Real-time ultrasound imaging of the neck's soft tissues was conducted. **Previous Imaging**: None to compare against. **Observations**: There are several small lymph nodes found in the submental area just beneath the chin, each measuring up to 6 mm. Notably, there is also an area measuring 9 x 9 x 5 mm that appears hypochoic, which lacks specificity. While this may indicate a lymph node, alternative lesions cannot be ruled out. No fluid accumulation was detected, and no additional lesions were observed. **Conclusion**: The presence of small lymph nodes in the submental area is noted. The hypochoic nodular region remains inconclusive. A CT scan of the neck with intravenous contrast is recommended for further assessment.
Is My Mouth Injury Infected?
A few days ago, I had a small growth in my mouth which my periodontist removed on Tuesday for a biopsy. They mentioned that it was probably not cancerous, but they wanted to confirm. After the procedure, I received stitches and experienced a lot of pain on the same day, prompting me to take Motrin. I felt better the next day, although some discomfort returned the following morning. Now that it’s Friday, the pain has significantly decreased. The area where the wound is located appears to have a slight white or yellowish tint, but I am unsure whether this is due to the stitches or if it could indicate an infection. Since the second day, I have been rinsing my mouth with salt water to aid healing. Unfortunately, my periodontist's office is closed until Monday. If anyone can provide some insights or advice, I would be very grateful! *Edit: The link to the image isn’t functioning. If you’re willing to help, I can send it via direct message.

Comparing Long-Term Use of Oxcarbazepine and Gabapentin
18-year-old male, 183 cm in height, weighing 67 kg. Greetings! I have previously used both oxcarbazepine and gabapentin to manage my Atypical Trigeminal Neuralgia. My experience with both medications has been generally positive, although I’ve noted that gabapentin tends to produce fewer side effects. At present, I’m taking 300 mg of gabapentin three times a day. My physician has allowed me to select the medication that I feel is most effective for my condition. However, I have reservations about the long-term safety of these drugs, and I am interested in gathering additional insights regarding which of the two might present a more favorable safety profile over an extended period.
Concerns About Pancreatic Cancer
Greetings, I am reaching out in search of encouragement or comfort, as I am becoming increasingly convinced that I may have pancreatic cancer. To provide some context, I am a 41-year-old male, married, and a father to three young children aged 5, 3, and 9 months. Currently, I am awaiting the results from a CT scan conducted nine days ago, which examined my pancreas, pelvis, and abdomen. My journey began about four months ago during a stressful period when I was concerned about having skin cancer. Unfortunately, I did indeed have a skin cancer diagnosis, but I was fortunate enough to catch it in time, and it was successfully removed. However, since that point, I have been troubled by persistent mid-back pain, located just left of my spine. Initially, this discomfort was sporadic, but over the past four months, it has escalated to a constant nagging sensation. While I typically manage the pain without medication, it remains a source of annoyance. Over the past four months, my anxiety surrounding health issues deepened as I sought to make sense of the back pain. My worries led me to contemplate dire scenarios, including skin cancer recurrence, followed by concerns about spinal and lung cancers. Thankfully, tests for these conditions returned negative. In the previous month, however, I've started experiencing additional discomfort, which has intensified my fears surrounding pancreatic cancer. Recently, I have developed abdominal pain primarily on the left side, occasionally beneath my ribs and around my navel. More troublingly, I have begun to experience strong flank pain that radiates to my side. The location of my back pain has also shifted; sometimes it's in the middle, at times between my shoulder blades, or, more recently, behind my ribcage. The abdominal pain is variable—it’s never excruciating, but it’s undeniably uncomfortable and persistent. Only by lying down or sitting can I find some relief. At times, it feels as though there’s an object lodged just beneath my sternum. Accompanying these symptoms has been a weight loss of 14 pounds over the past three months. Although this might be linked to my health anxieties, my weight has stabilized for the last two to three weeks. I have maintained a good appetite, but I frequently notice yellowish-brown stools, which can range from solid to soft. Additionally, my belching has increased throughout the day, and I've noticed a rise in flatulence over the past week or two. A variety of tests have been conducted recently: an abdominal ultrasound, blood work—including assessments for pancreatic and liver function, a CA19-9 marker test, and an MRI of my thoracic back—all of which yielded normal results. I also underwent an endoscopy, which revealed only mild gastritis. I apologize for the lengthy message, but these past four months have been immensely challenging, particularly with the anxiety of potentially being unable to be there for my young family. I’m hoping someone might offer some reassurance or suggest that these troubling symptoms could stem from something other than pancreatic cancer.
Possible Oversight in MRI Analysis During Vietnam Visit
I am a 37-year-old male, height 5'4" and weight 130 lbs, with a mixed Hispanic and White background. I consume alcohol sporadically, about 2 to 3 times per week, and I do not smoke. At the moment, I am not taking any medication. Recently, while on vacation in Vietnam, I underwent an MRI scan due to ongoing issues with focus and persistent brain fog, accompanied by a tingling sensation in my head. Considering the affordability of the MRI in Vietnam, I decided to proceed with it. During my consultation, the doctor diagnosed me with a mild sinus infection but didn't provide any further explanations. He presented me with a somewhat unclear black-and-white printout of my MRI, indicating the infected sinus cavity. My wife later bought me some over-the-counter sinus medication from a local pharmacy. Upon returning home, I accessed my MRI results via the clinic's website and noticed an orange arrow pointing to a white area on the scan. This has raised some concerns for me. Is this white spot something I should be worried about, or could it simply be a typical feature related to aging? I intend to schedule an appointment with my doctor to discuss this further.
