Anemia: Symptoms, Risks, and Prevention Strategies

Anemia-related issues

Recently, I had a blood test at the hospital with the following results: Hb 9.9, MCV 75.6, Hct 32.8, MCHC 22.8.
Due to certain reasons, I did not have my iron levels checked, but the doctor believes there is a high probability of iron deficiency anemia.
Here are some questions I would like to ask:
1.
Before my blood test, I went out with some classmates, and while walking, I started feeling increasingly dizzy and my vision became blurry.
I also turned pale, began sweating profusely, and felt like I was going to faint.
After my classmates bought me brown sugar pearl milk to drink, I started to feel better.
It was a hot day, and I had not been drinking much water.
Before experiencing those symptoms, I only had a scallion pancake with an egg.
Could this be a symptom of anemia?
2.
On that same day, while outdoors in the hot weather, I walked a short mountain trail for less than ten minutes and again felt dizzy and my face became increasingly pale.
However, this time I was continuously hydrating and had eaten.
Could this also be a symptom of anemia?
3.
Last year, I fainted during an outdoor activity and saw a doctor who diagnosed it as vasovagal syncope, which he said is a normal phenomenon.
My Hb level from a blood test last year was 10.9.
Could this be related to anemia as well?
4.
Is it common for individuals with anemia to experience dizziness during prolonged outdoor activities such as ball training, especially when also engaging in endurance and strength training?
5.
Could individuals with anemia be more prone to dizziness due to insufficient caloric intake, inadequate hydration, or electrolyte loss?
6.
What preventive measures can individuals with anemia take to avoid experiencing dizziness?
Thank you, doctor, for taking the time to clarify my concerns.

Hello! Based on the information you provided, it appears to be microcytic anemia, and there will be significant fluctuations in hemoglobin levels, indicating a higher likelihood of iron deficiency anemia.
Regarding the dizziness you mentioned, there are many potential causes, and anemia itself is one of them, especially in situations of rapid fluid loss (such as during menstruation or excessive sweating), which may become more pronounced.
If your blood pressure is generally not high, vigorous exercise and rapid changes in posture can also lead to dizziness.
I recommend visiting a hematology clinic to confirm the cause of your anemia, which will allow for more targeted prevention.
Thank you for your question! Wishing you a speedy recovery!

More Info

Anemia is a condition characterized by a deficiency of red blood cells or hemoglobin in the blood, which can lead to a variety of symptoms and complications. Based on your blood test results, which indicate low hemoglobin (Hb 9.9), low mean corpuscular volume (MCV 75.6), and low hematocrit (Hct 32.8), it is indeed likely that you are experiencing iron deficiency anemia. This condition can manifest in several ways, and your symptoms align with common presentations of anemia.

1. Symptoms of Anemia: The symptoms you described, such as dizziness, blurred vision, pallor, and sweating, are classic signs of anemia. When your body lacks sufficient hemoglobin to transport oxygen, it can lead to inadequate oxygen supply to the brain and other organs, causing dizziness and fainting. The fact that you felt better after consuming a sugary drink suggests that your body may have needed a quick source of energy, which can sometimes alleviate symptoms temporarily.

2. Physical Activity and Anemia: Engaging in physical activities, especially in hot weather, can exacerbate symptoms of anemia. Even if you were hydrating and eating, the combination of exertion and anemia can lead to increased fatigue and dizziness. Your body may struggle to meet the oxygen demands of your muscles during exercise, particularly if you are already anemic.

3. Vasovagal Syncope: The episode you experienced last year, which was diagnosed as vasovagal syncope, can indeed be related to anemia. This type of fainting occurs when the body overreacts to certain triggers, such as standing up too quickly or experiencing stress, which can be compounded by low hemoglobin levels. The previous Hb value of 10.9 indicates that you were already borderline anemic, which could have contributed to your fainting episode.

4. Training and Anemia: For individuals with anemia, participating in strenuous physical activities, such as sports training, can increase the risk of dizziness and fainting. The body’s ability to deliver oxygen to muscles is compromised, making it more challenging to perform at higher intensities. It is crucial for anemic individuals to monitor their symptoms closely during exercise and consider modifying their training intensity.

5. Hydration and Nutrition: Yes, inadequate caloric intake, insufficient hydration, and electrolyte imbalances can exacerbate dizziness in individuals with anemia. Proper nutrition is vital for managing anemia, as iron-rich foods (such as red meat, beans, and leafy greens) are essential for replenishing hemoglobin levels. Additionally, staying well-hydrated helps maintain blood volume and circulation, which is particularly important during physical activities.

6. Preventive Strategies: To prevent dizziness and other symptoms associated with anemia, consider the following strategies:
- Dietary Adjustments: Incorporate iron-rich foods into your diet, and consider vitamin C sources (like citrus fruits) to enhance iron absorption.

- Hydration: Ensure you are drinking enough fluids, especially during hot weather or when exercising.

- Monitor Symptoms: Pay attention to your body’s signals. If you feel dizzy or fatigued, take a break and rest.

- Consult Healthcare Providers: Regular check-ups with your healthcare provider can help monitor your hemoglobin levels and overall health. They may recommend iron supplements or further investigations if necessary.

In conclusion, your symptoms and experiences are consistent with anemia, and it is essential to address both the underlying causes and the symptoms. By making dietary changes, staying hydrated, and consulting with healthcare professionals, you can better manage your condition and reduce the risk of dizziness and other related symptoms.
