Understanding a Low Anion Gap Result
Recently, I underwent a comprehensive set of blood tests, including a complete blood count (CBC) and a comprehensive metabolic panel (CMP). While most results returned within the normal range, I noticed that my anion gap was on the lower side. As a 46-year-old female who does not smoke or drink alcohol, I maintain a fitness routine, strength training three to four times weekly. Overall, I feel quite well and prioritize a balanced diet. The only supplements I take are a daily multivitamin and creatine monohydrate, which I consume 3-4 times each week, albeit occasionally forgetting it. Here are my lab results: - Sodium: 137 (normal range: 136 - 144) - Chloride: 110 (normal range: 101 - 111) - CO2: 22 (normal range: 22 - 29) - Anion Gap: 5 (normal range: 7 - 16) All other parameters were normal, including potassium (4.4), albumin (4.3), total protein, and total globulin levels. No urine tests were conducted during this round of labs. Given this information, should I be concerned about the low anion gap? Would further testing be advisable?

A low anion gap can raise questions, but in your case, it may not be a significant concern given your overall health and normal lab results. Here’s a breakdown of what this means and actionable steps you can take.
Understanding the Low Anion Gap
The anion gap is a calculated value that helps assess the balance of electrolytes in your body, especially in relation to acid-base status. Normal values usually range from 7 to 16 mEq/L, and a low anion gap (like yours at 5) can sometimes indicate issues such as low albumin levels, certain types of kidney disease, or other electrolyte imbalances. Importantly, you mentioned that your albumin level is normal, which is a good sign.
Why You Might Not Need to Worry
- Your Health Status: Since you report feeling well, maintaining a healthy lifestyle, and your other lab results are normal, the low anion gap might not signify a serious issue.
- Common Variants: Low anion gaps can occur for various benign reasons, including laboratory variations or lifestyle factors.
Next Steps
-
Monitor Your Symptoms: Continue to pay attention to how you feel. If you experience unusual symptoms like fatigue, unusual muscle cramps, or swelling, take note of these changes.
-
Review Your Diet and Supplements: Ensure you're consuming a well-rounded diet that includes plenty of fruits and vegetables, as these can help balance electrolytes naturally. While your multivitamin is beneficial, consider consistency with your creatine intake and monitor how it may impact your hydration levels.
-
Follow-Up Testing: If you're still concerned about your low anion gap or if abnormal symptoms develop, discussing further tests with a healthcare provider, such as a urine analysis or additional electrolyte measurements, could provide more clarity.
-
Stay Hydrated and Active: Continuing your fitness routine is excellent. Adequate hydration is also essential, especially if you are supplementing with creatine.
By following these steps, you can keep track of your health and alleviate concerns about the low anion gap. If you notice any changes in your health status or have further questions, feel free to reach out for more information.

My Relationship with Milk Consumption
For nearly two decades, I have predominantly relied on milk as my primary source of hydration, consuming around five liters daily. Although I recognize that this reliance might not be the healthiest choice, my low appetite has perpetually left me underweight. In the past, I attempted to transition to drinking water; however, I noticed a concerning drop in weight along with persistent fatigue. My inquiry is whether there exists a more nutritious method to obtain calories without resorting to solid foods, and ideally, without incurring high costs?

Seeking Help for Ongoing Health Issues
I am reaching out in desperation for assistance! I'm wondering if anyone else has encountered similar health concerns or could recommend medications or specialists I should consider consulting. I'm truly at a loss and need guidance. As a 23-year-old male vegetarian weighing around 48 kg and standing at 5’4”, I have struggled with being underweight since my childhood. This condition has left me feeling utterly drained and overwhelmed. I’m eager to make a change but feel lost regarding where to begin or which healthcare professional to consult. In my youth, I was diagnosed with asthma, which has significantly improved; however, I continue to deal with low immunity, as I frequently catch colds and coughs from minor exposure to cold environments. Additionally, I’ve noticed that for the past few years, my body temperature feels abnormally high compared to those around me. I experience heat more acutely than my peers. Previously, I was quite active and could walk 4–5 kilometers daily without difficulty. Nowadays, even a short walk of 1–2 kilometers or climbing a few flights of stairs leaves me out of breath and exhausted. Even on days of little physical exertion, I feel weak and lethargic, as though all my vitality has been drained. My appetite has always been low, despite my efforts to increase it. I struggle to consume what would be considered an average meal for someone my age. Just two chapatis or a small bowl of rice or lentils fills me up completely, and attempting to eat more causes discomfort. I often find it perplexing how others manage to eat such larger portions. Dining out has become a challenge for me since even half a plate feels overwhelmingly full. Being extremely slender has made it difficult to find clothing that fits well and has adversely impacted my confidence over the years. For around 15 years, I have hesitated to take photographs of myself. Social and professional circles often regard me as younger than I am, sometimes even as a child, which has contributed to my feelings of invisibility and insecurity. My sensitivity to heat has intensified over the last few years. In seemingly normal room temperatures, I start sweating profusely while those around me remain comfortable. During cold weather, even in temperatures as low as 8°C, I don’t wear warm clothing, as I sweat excessively and feel anxious about overheating. The discomfort can escalate to a point where I feel faint from the heat. In my workplace, where the air conditioning is set at a standard temperature, I find it challenging. I begin to sweat visibly, leaving my clothes damp and prompting coworkers to inquire about my wellbeing. I often feel breathless and anxious that I might collapse if I remain there too long. This makes it very difficult to stay at the office or use public transportation, as even air-conditioned buses can feel uncomfortably warm to me. Over the past year, my situation has deteriorated further. I can no longer tolerate hot or even mildly spiced home-cooked meals, which I used to enjoy without issues. Now, even mildly spiced foods lead to excessive sweating, reddening of my face, and an intense burning sensation in my mouth, akin to consuming overly spicy dishes. As a result, my food intake has diminished even more. I often face ridicule for my dietary limitations, and I’m growing weary of trying to explain my condition, especially when my own family doesn't fully grasp the depth of my struggles, which adds to my distress. I am sharing my story because I truly need help. I wish to identify the underlying issues with my health and seek proper medical attention. If anyone has experienced similar problems or can recommend a suitable type of medical professional to consult, I would greatly appreciate your guidance and support during this challenging time. Thank you. 😭
