Concern About Elevated Bilirubin Levels Despite Normal Liver Function Tests
Greetings, I’m a 37-year-old man weighing 80 kg who abstains from alcohol and smoking. Recently, after experiencing some morning diarrhea accompanied by mild pain in my upper right abdomen, just beneath the ribs, my physician recommended a series of blood tests. Below are the findings: ### Hematology Results - **White Blood Cells**: 9.63 (10³/mm³) [Normal range: 3.91-10.90] - **Red Blood Cells**: 5.19 (10⁶/mm³) [Normal range: 4.44-5.61] - **Hemoglobin**: 15.4 g/dL [Normal range: 13.5-16.9] - **Hematocrit**: 46.1% [Normal range: 40.0-49.4] - **MCV**: 89 µ³ [Normal range: 82-96] - **MCH**: 29.7 pg [Normal range: 27.0-32.3] - **MCHC**: 33.4 g/dL [Normal range: 32.4-35.0] - **Platelets**: 305 (10³/mm³) [Normal range: 166-308] - **MPV**: 9.6 µ³ [Normal range: 9.3-12.1] - **RDW-CV**: 12.6% [Normal range: 12.0-13.6] ### Differential White Blood Cell Count - **Neutrophils**: 51.8% (4.98 (10³/mm³) [Normal range: 1.80-6.98]) - **Lymphocytes**: 38.1% (3.67 (10³/mm³) [Above normal: 1.26-3.35]) - **Monocytes**: 8.8% (0.85 (10³/mm³) [Normal range: 0.29-0.95]) - **Eosinophils**: 0.9% (0.09 (10³/mm³) [Normal range: 0.03-0.59]) - **Basophils**: 0.4% (0.04 (10³/mm³) [Normal range: 0.01-0.07]) ### Inflammation & Protein Assessments - **Erythrocyte Sedimentation Rate (ESR)**: 4 mm/hr [Normal: <15] - **C-reactive Protein (CRP)**: <0.5 mg/L [Normal: <5.0] ### Liver Function & Enzyme Evaluation - **Total Bilirubin**: 2.2 mg/dL [Reference range: 0.2-1.2] **(Elevated)** - **Direct Bilirubin**: 0.7 mg/dL [Reference range: <0.3] **(Elevated)** - **Indirect Bilirubin**: 1.5 mg/dL (calculated) - **AST (TGO)**: 21 U/L [Normal: <34] - **LDH**: 187.0 U/L [Normal range: 120.0-246.0] - **GGT**: 18 U/L [Normal: <73] - **Alkaline Phosphatase**: 55 U/L [Normal range: 46-116] - **Amylase**: 29 U/L [Normal: <118] ### Additional Context In my previous blood tests conducted last year, all values were within normal limits (total bilirubin was 1.3 mg/dL and direct bilirubin was 0.38 mg/dL). I was fasting, experiencing dehydration, and under considerable stress during the recent test. Currently, I have no signs of jaundice or dark-colored urine. The only ongoing symptom I have is the intermittent mild discomfort in my upper right abdomen and morning diarrhea. After taking loperamide, my stools return to normal consistency. I find myself feeling extremely anxious regarding these results. As I await feedback from my doctor, I hope to be equipped for our upcoming discussion. Are there particular concerns I should have or anticipate? Could benign factors clarify these test results? I appreciate your assistance!

It’s understandable to feel anxious about elevated bilirubin levels, especially when accompanied by gastrointestinal symptoms. Your test results indicate slightly elevated bilirubin levels, particularly the direct (conjugated) bilirubin, but your liver function tests—such as AST and alkaline phosphatase—are within normal ranges. This suggests that there may not be severe liver dysfunction at present.
Main Points:
- Elevated Bilirubin: The total and direct bilirubin levels are above normal.
- Liver Function Tests Normal: Essential liver enzymes indicate no significant liver damage.
- Symptoms & Context: Morning diarrhea and mild discomfort in the upper right abdomen could relate to bile processing issues or non-liver-related gastrointestinal concerns.
Explanation:
Bilirubin is a waste product from the breakdown of red blood cells and is processed by the liver. Elevated bilirubin can come from various benign or more serious factors, including:
- Dehydration: Based on your fast and dehydration during the test, bilirubin levels can rise.
- Stress: Stress can influence gastrointestinal health, leading to symptoms like diarrhea.
- Minor liver function disturbance: Given your mild symptoms and the normal liver enzyme levels, significant liver disease seems less likely.
Additionally, some people have a harmless increase in bilirubin due to genetic conditions (like Gilbert's syndrome) which do not cause health issues.
Next Steps:
- Hydration: Increase your fluid intake to alleviate any dehydration, as this may help normalize bilirubin levels.
- Monitor Symptoms: Keep a diary of your abdominal discomfort and bowel habits, noting any changes, persistence, or worsening symptoms.
- Manage Stress: Engage in stress-reduction techniques such as mindfulness, exercise, or hobbies to improve gastrointestinal symptoms.
- Recheck Bilirubin: Discuss with your doctor about repeating the bilirubin test after you're fully hydrated and no longer stressed, to see if levels normalize.
When to Seek Urgent Care:
- If you begin to experience jaundice (yellowing of the skin/eyes), significant pain in the abdomen, or significant changes in urine color (dark urine), seek medical attention promptly.
It's good to prepare for your discussion with your doctor. Ensure you bring up any new symptoms, your stress levels, and dietary habits that could impact digestion. Remember that many factors could explain these lab results, and with time and care, you may see improvement.

Experiencing Clear Fluid from Ear with No Discomfort: Should I Wait for My Appointment?
I am a healthy 57-year-old female, weighing 120 pounds and standing 5 feet 5 inches tall. My daily medications include 100 mg of Losartan for effectively managed high blood pressure, 200 mg of Lyrica taken twice daily for post-herpetic neuralgia, 100 mg of Synthroid following treatment for thyroid cancer, and a combination hormone replacement therapy patch. Additionally, I take Zyrtec and Flonase every day to combat allergies. Since October, I have been dealing with persistent tinnitus in my right ear, accompanied by some pressure and a muffled sensation. Recently, I've noticed that when I speak, it feels akin to the sensation I experience when my ears clear during a flight after chewing gum—my voice sounds amplified in my head. I've scheduled an appointment with a physician's assistant in an ear, nose, and throat (ENT) office for the end of March due to my worries about the tinnitus and any potential hearing impairment. Yesterday, I noticed that my ear emitted a clear fluid. Thankfully, there was no associated pain. The fluid was somewhat thicker than water, completely odorless—unlike the unpleasant discharge I recall from my daughter's ear infections—and there was no sign of blood. Could this indicate a perforated eardrum? I suspect this might be the case, but can this occur without an underlying infection? Should I seek attention sooner than my appointment in March? I would prefer to avoid urgent care during flu season; however, if this situation is serious, I am prepared to take precautions and visit.
Understanding the Increased Pain in My Foot While Reclining
At 30 years old, I am nearing the five-week mark since undergoing surgery on my metatarsals. I've encountered a troubling issue: I can’t seem to find comfort when lying down, whether it’s with my foot raised or lying flat. My pain level escalates to a severe 10 out of 10, unless my foot is making contact with the floor or I dangle my leg off the side of the bed so that my toes touch the ground. Is this situation typical for someone in my circumstances? Are there any suggestions that might assist me in getting a better night's sleep?
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!
Persistent Pain in Right Shoulder and Arm After Lifting
Hello, everyone! I’m a 23-year-old male and have been engaged in weightlifting for several years now. Recently, I’ve been struggling with ongoing discomfort in my right shoulder and arm, which I haven’t been able to accurately identify. The pain manifests during particular movements, especially with lateral raises or when my arm is raised to shoulder level while rotating my wrist. Certain pressing and pulling activities can also provoke this discomfort. Rather than feeling sharp, it’s a deep, nagging sensation that sometimes seems localized in the front area of the shoulder or at the biceps tendon, and at other times it feels more like it’s situated between the shoulder and upper arm. Fortunately, there’s no numbness or tingling involved. This issue began while I was working out. I decided to take a break for around two months, but when I returned, the pain persisted. After consulting a physician, I was diagnosed with bicipital tendinitis. Since then, I’ve reduced my upper-body workouts, completely steering clear of shoulder exercises and heavy lifting, and have begun a gentle rehabilitation regimen focusing on external rotations, pendulum movements, and scapular exercises. Despite adhering to this routine for about a week, I haven’t experienced any noticeable improvement. Is it typical for this type of tendon injury to require an extended period for recovery? At what point should I consider diagnostic imaging, such as an ultrasound or MRI? Additionally, are there frequent rehabilitation errors that might impede the healing process? I appreciate your insights in advance!
