Experiencing Dizziness and Rapid Heartbeat on Treadmill — Normal Heart Tests, Yet Anxious. What Could Be the Reason?
Greetings everyone, I'm a 32-year-old male. After consistently hitting the gym for a month, I encountered an alarming event on day 30. During my treadmill workout, I jogged for about five minutes before transitioning to a walk. Out of nowhere, I felt a surge in my heart rate, a wave of dizziness washed over me, and I almost lost consciousness. I managed to find a seat to compose myself. Subsequently, I visited the emergency room where they conducted an ECG and checked my Troponin levels along with other blood tests. All results were within normal ranges, apart from a minor increase in Troponin. This prompted the doctors to recommend an angiogram, which thankfully revealed no issues. After the procedure, I was sent home. However, merely four days later, I faced a similar episode that involved dizziness and an accelerating heartbeat. I returned to my doctor, who explained that symptoms like these might occur due to blood vessel constriction triggered by cold exposure or stress. He provided me with some medication. It's now been ten days, and I feel physically well, but I'm grappling with persistent anxiety, fear, and a low mood stemming from that frightening experience. Has anyone else gone through a comparable situation? I am eager to understand: • How can such experiences occur despite the majority of health assessments appearing normal? • Could factors like anxiety or intense exertion contribute to these symptoms? • What actions should I consider moving forward in terms of exercise, lifestyle changes, mental health strategies, and follow-up medical visits?

I'm glad you reached out, and I can appreciate how distressing these experiences must be for you. It's understandable to feel anxious after such episodes, especially when combined with physical strain and significant health assessments.
Here’s a structured response to your situation:
Main Points:
- Your symptoms can occur even with normal heart assessments.
- Anxiety and physical exertion may contribute to episodes of dizziness and rapid heartbeat.
- Implementing lifestyle changes, stress management strategies, and gradual exercise reintroduction can be beneficial.
Explanation:
Symptoms like dizziness and rapid heartbeat, even with normal heart tests, can sometimes be linked to anxiety, stress, or even a physical response to exertion. When you exercise intensely, your body goes through various changes, and if you are anxious, these changes can feel more pronounced. Hormones like adrenaline can also lead to increased heart rate and feelings of dizziness, especially when paired with intense exertion.
Your doctor’s concerns about blood vessel constriction due to cold or stress is valid. Physical responses vary significantly among individuals, and anxiety can exacerbate the symptoms as your body reacts strongly to stress.
Next Steps:
-
Gradual Return to Exercise:
- Start with lower intensity activities, such as brisk walking or cycling, to reintroduce your body to physical exertion. Gradually increase the intensity only when you feel comfortable.
- Consider warming up adequately before workouts to prevent sudden changes in exertion levels.
-
Manage Anxiety:
- Practice relaxation techniques such as deep breathing, meditation, or yoga. These can help reduce feelings of anxiety and improve your overall mood.
- Regularly reflect on your feelings and experiences, perhaps writing them down, as this can help process the fear associated with your episodes.
-
Lifestyle Modifications:
- Maintain a balanced diet to support overall health. Foods rich in omega-3 fatty acids, antioxidants, and magnesium can help support cardiovascular and mental health.
- Stay hydrated, as dehydration can also lead to dizziness.
-
Monitor Symptoms:
- Keep a record of your episodes, noting the circumstances surrounding each one, such as your level of activity, stressors, and any pre-existing feelings of anxiety. This can help identify triggers over time.
-
Follow-Up Medical Visits:
- Continue to touch base with your healthcare provider about your feelings of anxiety and any ongoing physical symptoms. This will also allow adjustments in your treatment or medications if necessary.
Remember that feeling anxious after such episodes is normal. With time, gradual adjustment, and support, you can regain confidence in your physical activities. If feelings of anxiety or depression persist or worsen, don't hesitate to reach out for a structured mental health support system.
Take care, and be kind to yourself as you navigate through this!

Are My Anti-Depressants the Wrong Choice?
Greetings everyone, I am a 25-year-old woman dealing with depression, mild anxiety, and some PTSD. I also experience hypermobility and have a heart murmur. My height is 170 cm, and my weight is 90 kg. I'm seeking guidance on whether the medication prescribed to me is the appropriate choice, as I'm concerned that, based on the label, it might not be suitable for me. In my younger years, I faced challenges with OCD, severe anxiety, and depression. Initially, I was given Escitalopram, which was effective for several years until my anxiety escalated dramatically, prompting a switch to Fluoxetine. During that transition, I realized I had been experiencing more side effects from Escitalopram than I initially recognized, such as significant sweating. After a little over a year on Fluoxetine, I felt better and chose to stop taking it, remaining medication-free for the last three years. However, in the past six months, my depression has worsened considerably. After consulting with my doctor, I resumed Fluoxetine treatment. Now, three weeks into this round of medication, I'm experiencing side effects that I may not necessarily link directly to the medication but still mentioned them during my follow-up. The symptoms include excessive sweating in my palms and feet, increased heart palpitations, and a two-week delay in my period. I've read that this medication can cause heavier menstrual bleeding, yet my pregnancy tests have all come back negative. This situation has left me quite perplexed. My doctor advised me to discontinue Fluoxetine and instead prescribed me Propranolol. To the best of my understanding, this medication is typically used for immediate relief of anxiety symptoms rather than addressing depression. The label also cautions against its use in individuals with pre-existing heart conditions or a history of self-harm, and it notes that it may lead to depression or suicidal thoughts. Is it correct for me to think that Propranolol is not classified as an anti-depressant? It seems odd that my GP would choose this to manage symptoms from a medication she told me to stop. I have already spoken with a former pharmacist, an occupational therapist, and am currently awaiting a callback from my pharmacy, as I expressed my concerns regarding the safety of this prescription. I'm feeling apprehensive about taking it, and I’m frustrated that my doctor has not considered prescribing a different anti-depressant. Any insights would be greatly appreciated. Keep in mind, I am not a medical professional—just someone navigating the complexities of mental health. I want to assure you all that I am safe and have support available for when I'm feeling vulnerable. At present, I do not have thoughts of harming myself or anyone else; I simply wish to be heard and find the right help.
Assessing Heavy Menstrual Bleeding: Should I Seek Emergency Care?
To condense my situation, I am now on the 21st day of my menstrual cycle with no sign of it concluding. The flow has been unusually heavy throughout, to the extent that I’ve had to change my menstrual discs within just a couple of hours due to overflow, accompanied by significant clotting. I visited a new gynecological office yesterday to establish care since my regular GYN won’t be available until June. However, this appointment allows me to see another clinician at the end of April. During my visit, we talked about scheduling a transvaginal ultrasound, and I began a course of medroxyprogesterone at a daily dosage of 10 mg, which I will take for the next ten days. Unfortunately, my night was quite troublesome, marked by excessive bleeding even with an ultra tampon in use. My primary concern right now is the risk of anemia. I ordered a CBC test through Labcorp on Monday out of sheer curiosity, which revealed my red blood cell count was at 3.64 and my hemoglobin level was at 10.9. The provider repeated the CBC along with an iron panel, and as of early yesterday afternoon, my results were: - Red Blood Cells: 3.3 - Hemoglobin: 9.9 - Hematocrit: 31 - Iron: 24 - Iron saturation percentage: 6 - Ferritin: 12 I am trying to remain calm and patient with the progression of events, but I recognize that I have been losing a considerable amount of blood since these tests. With the weekend here, I’m increasingly anxious as I likely won’t receive any updates until Monday. Do my lab results indicate the need for immediate medical attention? I intend to commence taking 325 mg of oral ferrous sulfate today to address my iron levels.
Seeking Guidance from India: Battling Burping Attacks During Exercise
At the age of 45, I maintain a lifestyle that involves no smoking or drinking. Employed in the IT sector, I typically have a sedentary routine and do not engage in regular physical activity. My body mass index (BMI) stands at 26, categorizing me as ‘skinny fat’—I’m not overweight, but I do possess some abdominal fat. My predominant concern arises when I attempt to exercise. Even after ensuring a three-hour interval post-meal, I frequently endure unexpected bouts of burping. These episodes are accompanied by a heavy, tight sensation in my chest, leading to breathing difficulties that provoke feelings of anxiety. Even mild exercises like cycling or performing two to three push-ups can trigger these episodes, and the discomfort persists for over an hour before finally easing. Interestingly, I do not experience heartburn or burping at any other time, only during or following physical exertion. I sought expertise from a gastroenterologist and underwent an endoscopy, which indicated mild gastritis but showed no signs of a hiatal hernia or other irregularities. Additionally, a cardiology assessment that included CT Coronary Angiography revealed no concerns, and a pulmonologist confirmed that my lung function is satisfactory. Due to my limited physical activity, my endurance is quite low. My desire to exercise and adopt a healthier lifestyle is strong, yet the sensations I feel—similar to air trapped in my chest wishing to escape—thwart my efforts. I've noticed that exercising on an empty stomach, particularly early in the morning, seems to stave off these burping issues. My professional environment is not overly demanding, which adds to my frustration. After incurring significant expenses for medical advice, I find myself at a loss with no clear indication of how to move forward. The root cause remains elusive and raises questions: Could it be linked to anxiety or stress? Even simple tasks, like playing football with my son or carrying heavy bags, can instigate these uncomfortable burping attacks, which linger for an hour or two. In this situation, I feel bewildered, disheartened, and utterly spent.
Navigating Alcohol Consumption While on Antidepressants
I am currently prescribed Escitalopram at a dosage of 10mg and Trazodone 50mg, which I take before bed for my mental health. Additionally, I use Clonazepam to help manage my anxiety. Earlier today, I joined a few friends for a social gathering where we had some drinks. I informed them that due to my medication, I usually avoid alcohol; however, I opted to have a single beer so I could participate in the festivities without feeling out of place. Now, approximately three hours later, I do not sense any lingering effects of alcohol. If there were any, they are quite subtle. My question is: Is it safe for me to take my medications in light of this?
Concerns About Potential Brain Damage at 16
To begin, I’d like to clarify that I’m currently located in Europe, where I observe that many individuals in my environment engage in more extreme behaviors than I do, even as I strive to partake in social activities without crossing the line into recklessness. My journey with alcohol commenced at the age of 14, albeit in a very mild manner. By the time I turned 15, I started drinking more regularly, making sure to space out my experiences approximately weekly to monthly, totaling around ten instances of intoxication. Notably, I noticed I had an adverse physical reaction to alcohol—specifically, skin flush the following day—which prompted me to transition to cannabis as it felt easier on my body. I limited my cannabis use to weekends while adhering to similar spacing, with one exception. At 16, I found myself smoking almost every day for a week after a particular incident, but I was able to regain control thereafter. When I was 15, I also experimented with psilocybin mushrooms on two occasions, which proved to be positive experiences and made me realize I needed to cut back on alcohol consumption. Recently, I had a successful experience with 150 micrograms of LSD after careful preparation. This evening, I intend to consume half an edible instead of resorting to drinking or smoking, aiming to increase my intervals between substances to once a month at a minimum while maintaining a healthy lifestyle as an athlete. Despite my efforts, my naturally anxious disposition makes me concerned about anything that may cause irreversible damage to my brain, including, for instance, excessive screen time. I would greatly value insights from professionals regarding these worries. For context: I’m 16 years old, assigned female at birth but have been on testosterone for seven months, standing at 5'4" and weighing 125 pounds.
