Presence of Ketones in Urine: Understanding the Implications
I am on a mission to shed some pounds and have adopted a low-carb, high-protein diet. So far, I've successfully dropped around 20 pounds over the last four months. Recently, I underwent blood tests and a urine examination, which revealed that I have +2 ketones in my urine. It's worth noting that I do not have diabetes; my fasting blood sugar level is 71, and my HbA1c is 5. Can anyone explain what might be causing this? Should I be concerned?

You've achieved significant weight loss through your low-carb, high-protein diet, and the presence of ketones in your urine can be a normal reaction to this dietary change. Let's break this down further and address your concerns.
Main Points:
- The presence of ketones in urine indicates that your body is using fat for energy instead of carbohydrates, a process known as ketosis.
- Ketones are typically harmless in the context of a well-managed low-carb diet, especially since you do not have diabetes and have normal blood sugar levels.
- Monitoring your progress and ensuring you remain healthy is essential.
Explanation: When you significantly reduce carbohydrate intake, your body shifts from using glucose (derived from carbs) as its primary fuel source to using fat, which produces ketones. This is a common metabolic state for those on low-carb diets and can contribute to weight loss. The levels of +2 ketones in urine indicate a moderate level of ketosis, which many low-carb dieters experience.
However, it is important to ensure that you do not progress into an unhealthy state, such as diabetic ketoacidosis, which is more common in individuals with uncontrolled diabetes. Since your blood sugar levels are normal, this is not a likely concern for you.
Next Steps:
- Stay Hydrated: Drink plenty of water to help flush out ketones and prevent dehydration.
- Monitor Symptoms: Keep an eye on how you feel. If you experience symptoms like nausea, vomiting, abdominal pain, or extreme fatigue, it might warrant further attention.
- Balanced Nutrition: Ensure you're getting a variety of nutrients. While a high-protein diet can aid weight loss, incorporate plenty of vegetables and healthy fats to support overall health.
- Consider Carb Cycling: If you're concerned about your ketone levels, you might explore a carb cycling approach, where you strategically include more carbs on certain days to balance your intake while still promoting fat loss.
- Regular Check-ups: Continue to monitor your health periodically, paying attention to how your body responds to your dietary choices.
It's great to see positive results from your weight-loss journey! Continue to listen to your body and adjust your approach as needed. If you have more questions about your diet or weight management strategies, feel free to ask.

Experiencing Unexplained Weight Loss and Sudden Alcohol Sensitivity
At 29 years old and standing at 6 feet, I've dealt with weight fluctuations all my life—oscillating between being slim and slightly heavier, but never quite reaching an unhealthy level. I have a history of anxiety, which I managed with medication after high school, but fortunately, I've been thriving without it for about three years. Since then, I've been free from panic attacks or related issues. However, roughly a year ago, I noticed an alarming change in my weight. For three years prior to this, I maintained a steady weight of around 210 pounds. This past year, though, I've lost an astonishing amount of weight, bringing me down to 160 pounds without making any significant changes to my diet. The only two major lifestyle adjustments I've made include: 1. Moving in with my mother and sister-in-law due to the high cost of our rental apartment while saving up for a home. This situation has undoubtedly increased my stress levels. 2. Taking on a supervisory role at a much busier rigging and crane company compared to my previous job. My work is physically demanding, averaging around 20,000 steps and climbing 37 flights of stairs daily, often encompassing 12 to 20-hour shifts, 6 to 7 days a week. I consulted my physician for a thorough physical examination and blood tests, all of which came back normal. She noted that I'm expending more calories than I consume, even though my wife insists that my eating habits are poor and quite substantial. It's puzzling why I'm not gaining weight. Another concerning development is my newfound intolerance to alcohol. Historically, I've had no issues enjoying 1-2 beers a night for the past eight years and could indulge in 9-10 beers or multiple glasses of whiskey without feeling any effects. Just last night, after having one old fashioned with a meal, I felt unwell afterward. This isn't an isolated incident; a few days ago, after consuming three beers while out, I abruptly stopped because I felt unexpectedly intoxicated, which I typically avoid. Could there be an underlying issue causing these symptoms, or is it simply a matter of not consuming enough calories? As far as I can tell, I have no other health complaints. My energy levels remain high, even with just 5 to 6 hours of sleep on average.
Is My Cat Bite Serious Enough for a Trip to the ER?
Around a day ago, I was bitten by my cat, and while the injury doesn’t appear to be infected, I’m experiencing significant soreness in my thigh. Should I consider going to the emergency room? First off, my cat is up to date on vaccinations. After the bite, I did clean the area with an alcohol wipe; however, I neglected to rinse it with running water, which I realize now was a mistake. This isn’t the first time my cat has bitten me, but the pain and discomfort this time are greater than usual, and it’s causing me some concern. There’s no heat around the wound, and the swelling is localized to the bite site. Should I consult a doctor about obtaining antibiotics as a precaution? A little about me: I’m a 28-year-old female, stand at 5 feet 3 inches tall, weigh 105 pounds, and don’t take any medications. I also vape and don’t have any ongoing health issues diagnosed. Unfortunately, I can’t upload an image here due to community restrictions, but I will attempt to share one in the comments section later.
