Q. What is it about grapefruit that most people on heart medication cannot eat them?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Grapefruit contains high levels of a compound called furanocoumarins, which can interfere with the way certain heart medications are metabolized in the body. Furanocoumarins give grapefruits their bitter or sour taste and also act as natural insecticides.
When you consume grapefruit, these furanocoumarins interact with enzymes in your intestine to block an important enzyme called CYP3A4. This enzyme is responsible for breaking down certain drugs that people take for their hearts, including statins and calcium channel blockers. In essence, when you eat grapefruit while taking heart medication, more of that medication ends up circulating in your bloodstream than normal because it isn't being broken down properly by CYP3A4.
This can increase the drug's activity level beyond what was intended and may cause serious side effects such as an abnormally slow or irregular heartbeat, a sharp drop in blood pressure (hypotension), dizziness, fainting spells (syncope) or kidney failure. In rare cases it can even lead to death if left untreated.
For this reason doctors generally recommend avoiding all forms of grapefruit products when taking any type of cardiovascular medication such as angiotensin-converting enzyme inhibitors (ACEs), beta-blockers or statin drugs like atorvastatin (Lipitor).

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.
