Experiencing Lightheadedness for Two Months | Male, 30
Sex: Male Age: 30 Years Current Medication: Hydroxyzine 50mg (for over a decade) prescribed for insomnia. Concern: I've been dealing with episodes of lightheadedness for approximately two months now, fluctuating from mild to moderate severity, with a couple of instances being quite severe. I have a follow-up appointment with my physician on Tuesday, and I'm seeking clarity on whether any of my test results might explain this persistent issue. Additionally, if this condition isn't a matter that warrants further investigation, I would greatly appreciate any recommendations for tests or treatments that I can discuss with my doctor to help manage the symptoms. Among the tests I underwent was a blood glucose level assessment which returned a result of 94 mg/dL, taken an hour and a half post-breakfast. Given that my mother has type 2 diabetes, she advised that such a reading isn’t typical unless fasting. To gather more data, I enlisted her assistance in testing my levels at home across different days. Below are the results of those tests (note that fasting occurred on a different day from subsequent tests): - 15 Minutes after Lunch: 84 mg/dL - 1 Hour after Lunch: 95 mg/dL - 2 Hours 30 Minutes after Lunch: 98 mg/dL - 1.5 Hours after Dinner: 99 mg/dL - Fasting for 8 Hours: 88 mg/dL Could these glucose readings possibly be the reason for my lightheadedness? Is there a particular reason my levels remain under 100 mg/dL? Are the standard post-meal glucose ranges of 140-170 mg/dL applicable only to diabetics, or should they be a concern for those without diabetes as well? With my glucose levels appearing stable, I take it as a sign that my pancreas is functioning adequately, but I’m uncertain if that’s the correct interpretation. In case my blood sugar levels turn out not to be the underlying issue, here are results from other tests conducted (not all of which were related to my lightheadedness, but we conducted a series of lab tests): - White Blood Cell Count (WBC): 6.0 (normal) - Red Blood Cell Count (RBC): 5.93 (moderately high) - Hemoglobin: 16.9 (normal) - Hematocrit: 51.4 (high) - MCV: 87 (normal) - MCH: 28.5 (normal) - MCHC: 32.9 (normal) - RDW: 12 (normal) - Platelets: 247 (normal) - Absolute Neutrophils: 3.3 (normal) - Absolute Lymphocytes: 2.1 (normal) - Absolute Monocytes: 0.4 (normal) - Absolute Eosinophils: 0.1 (normal) - Absolute Basophils: 0 (normal) - Immature Granulocytes: 0.0 (normal) - Glucose Level: 94 (normal) - Blood Urea Nitrogen (BUN): 16 (normal) - BUN/Creatinine Ratio: 15 (normal) - Sodium: 144 (normal) - Potassium: 4.6 (normal) - Chloride: 106 (normal) - Total Carbon Dioxide: 21 (normal) - Calcium: 9.6 (normal) - Total Protein: 7.2 (normal) - Albumin: 4.6 (normal) - Total Globulin: 2.6 (normal) - Total Bilirubin: 0.4 (normal) - Alkaline Phosphatase: 100 (normal) - AST (SGOT): 23 (normal) - ALT (SGPT): 47 (moderately high) - Total Iron Binding Capacity (TIBC): 340 (normal) - Unsaturated Iron Binding Capacity (UIBC): 258 (normal) - Iron Level: 82 (normal) - Iron Saturation: 24 (normal) - TSH with Free T4: TSH 1.050 | GGT 45 (results not marked) - Ferritin: 153 (normal) Diet: I maintain a consistent diet, with all meals prepared from scratch, avoiding fast food. Here’s a summary of what I typically eat: - **Breakfast**: 2 scrambled eggs on buttered whole wheat toast with a slice of pepperjack cheese. - **Lunch**: A salad containing red leaf lettuce, arugula, grilled chicken, seasoned black beans, peppers, tomatoes, assorted nuts, dried cranberries, shredded pepperjack cheese, green onions, and I dress it with half a squeezed lime; I pair it with either half a cup of brown rice or a slice of toast as a carbohydrate source. - **Dinner**: A protein bowl with shredded chicken, black beans, a cup of mixed vegetables (corn, green beans, carrots, peas), tomatoes, onions, and green onions, served over half a cup of brown rice, with added pepperjack cheese and topped with arugula/red leaf lettuce. - **Evening Snack**: 1 cup of yogurt, and I have 2 slices of whole wheat toast during the night. Given my dietary habits and test outcomes, what would be the best path forward to address my lightheadedness? Should I explore my glucose levels further? Are there additional tests to consider discussing with my doctor to find potential answers? What type of specialist would be best suited to consult regarding this issue?

It sounds like your episodes of lightheadedness have been concerning and ongoing. Given your specific health details, let's unpack this step by step, considering your symptoms, test results, and dietary habits.
Main Points:
- Lightheadedness can stem from various factors, including blood sugar fluctuations, hydration issues, or blood pressure changes.
- Your glucose readings are within a normal range and likely are not the direct cause of your symptoms.
- Some aspects in your blood test results may warrant further exploration.
Explanation:
Lightheadedness can arise from multiple causes, including low blood pressure, dehydration, or even side effects from medications like hydroxyzine. It's essential to assess and monitor any potential triggers.
Your glucose readings (all below 100 mg/dL) fall within the normal range for fasting and postprandial (after meal) states for someone without diabetes. The ranges you refer to for post-meal glucose apply more to individuals with diabetes and would not be a concern for someone with normal glucose tolerance.
The moderately high red blood cell count (RBC) and hematocrit may indicate dehydration, as they can increase when the body lacks sufficient fluids. Staying well-hydrated can help mitigate this effect.
Next Steps:
-
Hydration: Increase your water intake throughout the day. Aim for at least 8 to 10 glasses daily, especially if you engage in physical activity or live in a hot environment.
-
Monitor Symptoms: Keep track of when your lightheadedness occurs, including any triggers (such as after meals, standing up quickly, or specific activities). This information can be valuable for your doctor.
-
Discuss Medication: Since you’ve been on hydroxyzine for a long time, ask your physician if your medication could be contributing to your lightheadedness. They might consider adjusting the dosage or switching to a different medication for insomnia if necessary.
-
Review Blood Pressure: Since lightheadedness can be related to blood pressure, it might be beneficial to check your blood pressure regularly at home over the next few days.
-
Additional Tests: Discuss the possibility of further tests to assess hydration status, such as blood tests for electrolytes, as well as a complete blood count (CBC) to further investigate your elevated RBC count if symptoms persist.
-
Specialist Referral: If symptoms continue, it may be beneficial to discuss with your physician the option of seeing an endocrinologist to evaluate any potential metabolic issues, or a neurologist if the lightheadedness has neurological implications.
-
Healthy Eating: Maintain your nutritious diet, but consider reducing caffeine or alcohol intake, as they can sometimes contribute to dehydration or fluctuations in blood pressure.
Keep a note of these points and share them with your physician during your upcoming appointment. This will foster a productive dialogue about the potential next steps in diagnosing and managing your lightheadedness. Your proactive approach is commendable, and together with your doctor, you can work towards finding relief.

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!
