Understanding the Causes of Extremely Low ALT Levels
Greetings, I’m facing a perplexing situation concerning my blood tests and, despite my efforts to research this, I haven’t found clear answers. Generally, a low ALT level is considered favorable, yet my case seems unusual, and I’m hoping someone might offer some insight. I have been dealing with serious health concerns for quite some time. Historically, my ALT levels have consistently ranged from 0.15 to 0.17 across about ten tests since my childhood. However, I recently completed two tests: the first at the start of 2024, which showed an ALT level of 0.08, and another in 2025 that returned the same result of 0.08. I’m curious about the potential diseases that could lead to low ALT or possibly affect enzyme levels overall. Could cardiac issues contribute to this condition? I understand chronic kidney disease (CKD) may cause low ALT levels, but I am seeking other possible explanations. Fortunately, my liver appears to be functioning well, so that possibility is eliminated. I would appreciate any information regarding other diseases that could result in low ALT levels. As a 27-year-old female, I exhibit other indicators associated with chronic kidney disease along with symptoms suggesting cardiovascular problems, including swelling, difficulty breathing, a slightly elevated pulse, worsening conditions with minimal exertion, and digestive issues. My urine test indicated slightly high albumin levels, and my GFR is marginally low. I am currently in the diagnostic phase and have an abdominal ultrasound scheduled. However, I would like to get clarification about my ALT levels, as my physician is also unclear on the matter.

It sounds like you are going through a challenging time with your health and your low ALT levels, especially considering your symptoms and medical history. Understanding your concerns, I want to provide some clarity regarding low ALT levels and their possible implications.
Main Points
Low ALT (alanine aminotransferase) levels can be somewhat perplexing, as it is typically seen as a sign of good liver health. However, persistent low levels, especially combined with your other symptoms, may indicate underlying conditions worth investigating further.
Explanation
ALT is an enzyme primarily found in the liver, and while elevated levels can signal liver damage or disease, low levels—like the ones you've reported—are less common and typically not concerning by themselves if liver function is otherwise normal. However, low ALT levels can arise from several factors:
- Chronic Kidney Disease (CKD): As you mentioned, CKD can affect various metabolic processes and lead to low enzyme levels.
- Malnutrition or Nutrient Deficiencies: Lack of certain vitamins (like B6) can affect enzyme production.
- Genetic Factors: Conditions like hypobetalipoproteinemia can lead to low ALT levels without significant health issues.
- Other Health Conditions: Some autoimmune disorders or chronic illnesses might also affect ALT levels, although they are less common.
Symptoms and Potential Concerns
Given your history and presenting symptoms (such as swelling, difficulty breathing, elevated pulse, and digestive issues), it’s important to monitor these closely. Your symptoms, combined with high albumin in urine and a marginally low glomerular filtration rate (GFR), could indeed suggest cardiovascular issues along with kidney considerations that require comprehensive evaluation.
Next Steps
- Continue with Diagnostic Testing: You already have an abdominal ultrasound scheduled, which is a crucial step in assessing internal organs and possible abnormalities.
- Keep a Detailed Symptom Journal: Track any changes in your symptoms, including their frequency and severity. This can be valuable information for your healthcare team.
- Hydration and Nutrition: Ensure you are well-hydrated and consume a balanced diet rich in essential nutrients. If you suspect specific deficiencies (like vitamins), consider discussing this with a healthcare provider.
- Follow-up on Abnormal Tests: Stay in close communication with your healthcare provider about your test results and any new symptoms that may arise.
It's commendable that you're proactive about your health. I encourage you to maintain open communication with your healthcare team about your concerns, especially regarding your symptoms and how they relate to your ALT levels. You deserve clear answers and supportive care.

Assessing My Health Concerns: How Anxious Should I Be?
I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.
Understanding Possible Seizure Triggers and Recurrence Risks
Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!
Understanding EEG Results for My 22-Month-Old Son: Insights Needed
Could someone help clarify this for me? My son, who is just 22 months old, hasn’t started walking yet, becomes tired easily, and has been experiencing behavioral outbursts. He had a febrile seizure in February 2025, followed by another unexplained seizure in April 2025, which led us to consult a neurologist. Since he was 3 months old, he has been receiving therapy from a physical therapist for torticollis. At birth, he spent five days in the NICU due to issues with meconium aspiration. A recent MRI showed normal results, and he also had a follow-up EEG after one conducted in July 2025. The results from this recent EEG were abnormal for a pediatric patient in awake, drowsy, and sleeping states. Notably, there were brief episodes of left frontotemporal delta slowing, which occurred mainly when he was awake and drowsy. There were no signs of epileptiform activity detected. In contrast, the EEG performed back on July 3, 2025, was deemed normal for both awake and drowsy states, again with no evidence of epileptiform irregularities, although it did not capture any sleep data. This examination was prompted by the child's existing history of febrile seizures. Importantly, he is not currently on any anti-seizure medications. The EEG procedure used standard electrode placements per the 10-20 system, conducted a single-lead EKG, and included continuous video monitoring. During the analysis, the background activity was symmetric, indicating some anterior-posterior (AP) organization, with a dominant rhythm of 50-80 microvolts at 7 Hz. His drowsy state was marked by a reduced amount of eye blink activity, less breathing motion interference, and a generalized slowing in theta/delta frequencies. Stage II sleep exhibited spindles and vertex waves patterns. Additionally, there were intermittent bursts of 250-300 microvolts in the left frontotemporal region with semi-rhythmic activity of 2-4 Hz, mostly observed during wakefulness and drowsiness. No definitive epileptiform discharge was noted. Photic stimulation during the test did not elicit a strong response, and hyperventilation was not conducted during this session.
INTENSE Spine Discomfort, Breathing Difficulties, Muscle Twitches, and Sweating
To elaborate on the situation mentioned in the title, I’ve been experiencing unusual muscle twitches and spasms for the past few days, along with some discomfort in my back. However, today, I felt an unexpected sharp pain shoot through my spine, which has left my legs feeling numb and made it impossible for me to sit up straight. Additionally, I’ve been dealing with cold sweats for the last hour and struggling to breathe properly. Perhaps I’m just overanalyzing things and it’s a common occurrence, but the intensity of the pain is overwhelming—it's truly unbearable. I’m shaking quite a bit, and unfortunately, my parents aren’t responding to my attempts to reach them for help. I have a history of a chronic heart condition and arthritis, yet I’ve never experienced pain this severe, especially in my spine. For context, I am nearly 15 years old and female. My current medications include pain relievers, anxiety medication, beta blockers, and some vitamins, though those specifics may not be particularly relevant. I don’t smoke; however, I have tried vaping a few times, which might not matter much, but I thought it was worth mentioning as it was requested.
28-Year-Old Male Experiencing Scalp Sensations Post-Amitriptyline Treatment
I am a 28-year-old man in generally good health, without any cardiac concerns. Approximately a month ago, I encountered intense pain localized to one side of my head, which was unresponsive to paracetamol. However, a single dose of a migraine treatment provided substantial relief. Following that, I began a regimen of amitriptyline, starting at a nightly dose of 10 to 25 mg. While my head pain has diminished significantly—by about 90 to 95%—I now experience occasional uncomfortable sensations on my scalp. These feelings include pins and needles, a cooling sensation, and some crawling feelings near my hairline and ears. There are fleeting moments where I feel brief throbs lasting a second, but I do not have any persistent headaches. To clarify, I do not experience any of the following: - Nausea - Weakness in my limbs - Numbness - Changes in my vision - Coordination difficulties - Seizures The symptoms I have are transient, shifting around and often intensifying when I become conscious of them or as the day progresses. I would like to know: Is it common to experience these sensations during the recovery stage following episodes of neuralgia or migraine-like discomfort? Additionally, could the amitriptyline potentially be causing these temporary paresthetic sensations? I am seeking some reassurance or advice on what is typically observed during this healing process. Thank you.
