What Causes My Fainting During Workouts?

6/21/2025, 4:00:56 AMMale25-34

Age 18, Weight 102 lbs, Height 5'2", No medications I’m curious to find out if there’s a particular health concern I should investigate. When I engage in exercises that require swift movements, such as shuttle runs or burpees, I often feel lightheaded and may even faint unless I take a moment to rest. It’s puzzling because not all workouts leave me feeling drained, and I wonder if this is solely due to low blood sugar. Additionally, in my everyday life, I experience dizziness when I rotate my head quickly or make too many quick movements.

Feeling lightheaded or faint during workouts can be concerning, especially at your age and activity level. Several factors could contribute to this experience, including dehydration, low blood sugar, or issues with blood circulation. It’s important to explore what’s happening in your body to ensure your safety during exercise.

Explanation

When you engage in high-intensity workouts that involve quick movements, your body requires a sufficient supply of blood and oxygen to function effectively. Factors such as not drinking enough fluids, not eating properly before exercise, or even blood pressure changes can lead to feelings of dizziness or faintness. Additionally, if you experience dizziness with quick head movements in daily life, it could indicate a vestibular issue or other imbalance.

Next Steps

  1. Stay Hydrated: Ensure you're drinking enough water throughout the day, especially before and during exercise. Dehydration can contribute to dizziness.

  2. Nutrition Before Workouts: Eat a balanced meal or snack before exercising. Focus on carbohydrates and proteins. For example, a banana with nut butter or a small smoothie can provide energy. Avoid workouts on an empty stomach.

  3. Gradual Movements: When changing positions or moving quickly, try to do so gradually. This can help your body adjust and reduce dizziness.

  4. Pace Yourself: During intense workouts, intersperse rest periods. If you start feeling lightheaded, take a moment to rest and recover before continuing.

  5. Monitor Symptoms: Keep a diary of when these symptoms occur, including what you ate, when you last ate, your hydration levels, and the types of workouts you're doing. This can help identify patterns.

  6. Consider Breathing Techniques: Focus on your breathing during workouts. Deep, controlled breaths can help increase oxygen flow and ease feelings of lightheadedness.

If your symptoms persist despite these adjustments, consider seeking professional guidance or a doctor’s opinion for a more thorough evaluation. Staying safe and healthy during your workouts is essential. Let me know if you have further questions or need more specific advice!

Concerns about Food Aspiration

Hello, I'm a 23-year-old female, currently using pregabalin to manage chronic migraines. Recently, I made the unfortunate choice to chat while indulging in a soft chocolate bar. This happened about thirty minutes ago, and ever since, I’ve been anxious about the possibility of aspirating some of the chocolate. Shortly after eating, I noticed an unusual sensation in my throat—nothing painful, but definitely off, accompanied by a strange feeling in my neck. Although I haven’t experienced any coughing or the typical sensation of something going the wrong way, I’m still feeling a bit odd in my throat and neck area. Additionally, I had some belching and felt a wave of dizziness right after the incident, which I’m still experiencing to some extent. I'm genuinely worried about the risk of developing aspiration pneumonia, and it’s causing me a lot of stress.

Is Eating an Old Starburst Safe?

Recently, I sampled a Starburst that I saved from last Halloween. I’m 9 years old, roughly 4 feet tall, and weigh about 80 pounds. The packaging looked perfectly intact, and the wrappers seemed fine too. The candy itself didn’t show any signs of spoilage, such as browning or mold. I also made sure to wash it before eating. Should I be concerned about this choice?

Seeking Advice for Ingrown Toenail Care

Hello, I'm a 17-year-old male dealing with an ingrown toenail issue. I underwent surgery to address it a few months back, and while it initially healed well, I've noticed it's not looking quite right again. My plan is to soak my foot nightly in a warm bath with Dettol for about 20 minutes over the next two weeks before consulting with a professional for further treatment and medication. I would really appreciate any additional suggestions or remedies you might have to help manage this situation.

Inquiry about Genetic Testing and Its Implications

Age 45, height 5'4", weight 240 lbs, Caucasian; has a background of polycystic ovary syndrome (PCOS) and obesity (achieved a weight loss of 74 pounds over the last two years); suffers from hypertension and elevated cholesterol levels; has endured various joint injuries due to an accident that required lumbar fusion from L3 to S1, along with reconstructive surgeries on the shoulder, ankle, and knee; experiences anxiety, depression, and migraines. I recently underwent comprehensive genome sequencing and discovered several significant abnormalities that require consultation with an endocrinologist. I am interested to know how healthcare providers react when patients present these types of findings. My intention is not to come across as demanding or to imply that I possess greater knowledge than my physician. However, after numerous tests and persistent efforts to seek answers over the years, I feel that we may have uncovered a genuine explanation for my symptoms, and I wish to ensure that my concerns are acknowledged and taken seriously.

Inquiry About Dental Procedures Before Major Surgery

Recently, my mother made a sudden decision to undergo a total dental extraction. She had her upper teeth removed approximately two weeks ago, and just yesterday, the lower ones were taken out. She is slated for a pre-operative assessment on Monday morning, ahead of a significant back surgery scheduled for Tuesday, which may last between eight to ten hours and necessitates intubation. I am curious about the likelihood that her doctor might postpone the surgery due to her recent dental procedure. This concern is heightened as we have booked a hotel and my husband has arranged to take two days off work for this event. Although I am still within the timeframe to cancel our hotel reservation, I am hesitant to do so if her surgery is still on track. To give a bit more context, my mother is a 54-year-old Caucasian woman, standing 5'6" and weighing 160 pounds. She does not consume alcohol, has been a potential smoker, and recently (a few months back) ceased using drugs (meth) as mandated by drug court. As far as I know, she isn’t currently prescribed any medications, apart from possibly antibiotics and Lortabs following her tooth extractions.
