Q. Why is there no cyanosis in severe anaemia?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Cyanosis is the bluish or purplish discoloration of the skin and mucous membranes that occurs when there's not enough oxygen in the blood to turn it red. In severe anaemia, a person's red blood cell count has dropped significantly, leading to insufficient oxygen-carrying capacity. As such, even if there was cyanosis present, it may be difficult for a doctor or clinician to detect as the individual’s overall reduced red blood cell count would keep any cyanotic areas from standing out against non-cyanotic ones. On top of this physiological barrier, typical causes of cyanosis are also absent in anemic patients due to their low iron levels; these include hypoventilation and right side heart failure (the body’s white cells can't take up iron molecules).
That being said, while individuals with severe anaemia may not exhibit physical signs of cyanosis as outwardly visible on their skin or mucous membranes due to lower hemoglobin counts compared with those without anemia, superficial tissues can still appear pale - at least more than normal - which can be linked with an insufficient amount of circulating hemoglobin (and therefore oxygen) throughout the body.

Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
