Q: I have high blood pressure and allergy. Are allergy drugs OK for me?

Allergic reactions occur when the defense system of the body, the so called immune system, mistakenly considers certain substances as harmful and fights against them. These substances are called “allergens”.  This fight will be expressed by our body as skin rash, itching, runny nose or allergic shock which is a severe reaction to an allergen.

Q: What causes tinnitus? High blood pressure may cause tinnitus?

Tinnitus is the perception of ringing in the ears. It is a common problem affecting 1 to 5 people. Tinnitus is not a disease but a symptom of some other diseases and conditions like:

  • Age-related hearing loss
  • Ear injury
  • High pitched sounds
  • Circulatory system diseases
  • High blood pressure
  • Meniere’s syndrome
  • Stress
  • Ear infections
  • Head and neck tumors

It may be transient or it can be heard all the time in one or both ears. High blood pressure could be a cause of tinnitus. It that case tinnitus is heard in both ears and is pulsatile i.e follows the heart beat. When blood passes under high pressure through narrowed blood vessels it makes a noise so intense that can stimulate the hearing nerve.

Q: I have mildly elevated blood pressure. Do I need medication?

It is not clear if blood pressure drugs help in case that your blood pressure is mildly increased (140-159 systolic and/or 90-99 diastolic) because the potential benefits are less than the risk of side effects.
Life style changes in that case, are more beneficial than drugs, if the only health problem you have is high blood pressure. Keep in mind that very low systolic pressure is bad for elderly people because of the risk for ischemic stroke. Atherosclerosis causes loss of blood vessel elasticity rendering them stiff and narrow so less blood goes to the brain and other organs. And while young adults have addaptive mechanisms to deal with this, elderly people do not. One of the bad consequences of this could be an ischemic stroke.


Q: Does running increase my blood pressure?

During running and other aerobic exercises, blood pressure normally rises to meet the increased needs of the body in oxygen. People that do not routinely exercise are more likely to experience increases in their blood pressure and heart rate. Although mild blood pressure rising is not a concern for most people, extreme elevations could be a red flag for future hypertension.

Q: Why I have high blood pressure after delivery and breast feeding?

Hypertension affects 6-10% of pregnancies, but there are few studies about incidence of high blood pressure after delivery. The most common cause of postpartum hypertension is high blood pressure during pregnancy or pre-eclampsia that persists after delivery. Women with pre-eclampsia have a 3.7-fold increased risk to develop high blood pressure in the future. Besides it is not uncommon for pre-eclampsia to appear for the first time after delivery. If your blood preassure readings remain high for more than 6 weeks after delivery, you should consult a specialist.
Hypertension is not itself a contraindication to breastfeeding, but certain medications for high blood pressure may be an issue. You should not breastfeed if have been prescribed any type of diuretics (i.e water pills).

Q: Why my blood pressure has increased since I quitted smoking

Blood pressure increases transiently while smoking a cigarette or when exposed to passive smoking and returns to the initial levels 20 minutes after. Some observations suggest a transient increase Later, stable high blood pressure may occur as a result of blood vessel damage caused by smoking. Even if your blood pressure was normal by the period you were smoking, you may observe that your readings began to increase after you started to quit. Usually there is nothing to worry about, unless your blood pressure spikes far exceed the normal values or last longer than 1-2 weeks. So if you decide to join a smoking quitting program, your doctor may prescribe you antihypertensive drugs to prevent eventual blood pressure spikes.

Q: How Can High Blood Pressure Cause Heart Attack?

High blood pressure progressively leads to hardening of all blood vessels in the body including the coronary arteries that supply the heart muscle. As a consequence, the coronary arteries slowly, become narrowed, limiting the amount of blood flow in the heart. Without oxygen the heart muscle is unable to contract efficiently and suddenly stops its activity, that is heart attack.

Q: What is considered high blood pressure emergency?

Hypertensive crisis comprises two clinical entities: hypertensive urgency and hypertensive emergency. Both of these conditions can occur when blood pressure exceeds the upper limits.
Hypertensive Urgency
Blood pressure spikes with readings of 180/110 or higher but there is no potential damage to the body’s organs. Blood pressure can be lowered within a few hours with blood pressure medication.
Hypertensive Emergency
Blood pressure increases to the point that organ damage can occur. Immediate hospitalization and is needed to prevent irreversible organ damage.

Brain damage manifested as confusion and other changes in mental status
Stroke signs
Unstable angina
Acute Heart failure
