Blood pressure spikes can be life-threatening, especially in older adults, causing cardiovascular, kidney, and eye issues.
Illnesses can significantly worsen physiological conditions. They activate multiple biological systems simultaneously, resulting in a significant rise in blood pressure. Besides acute illnesses, an aging cardiovascular system also affects blood pressure changes in older adults.
Understanding how blood pressure increases affect the elderly is crucial to choosing the best emergency medical device for them. It will be particularly useful for those with ongoing health issues who require special care.
This guide is a comprehensive breakdown of the core biological mechanisms causing this response in older adults.
How Aging Affects Blood Pressure Regulation
The question, “does blood pressure can go up when senior is sick” has a clear physiological basis.
People of all ages experience changes in blood pressure, which is quite normal depending on the situation. The baseline physiology of aging is worth considering before examining the link between blood pressure and illnesses.
As people age, their blood vessels (arteries) become narrower, stiffer, and less responsive. This happens when the vessel walls’ structure changes as the elasticity declines over time. As a result, higher than usual pressure will be necessary to circulate blood effectively.
There’s more. While the vessel walls struggle to push blood, the baroreceptor sensitivity declines as the vascular dilation becomes less efficient.
The implication can be severe. When stressors, such as infection or inflammation, surface, the aging body cannot regulate blood pressure as effectively as a younger one.
What Happens During Illness
When humans get ill, the body enters a defensive state. It triggers several overlapping mechanisms almost at once, resulting in the following reactions:
1. Stress Hormone Surge
Illness activates stress hormones like cortisol and adrenaline. These hormones increase heart rate, shrink blood vessels, and raise cardiac output. They cause an intentional rise in blood pressure.
This intentional condition aims to ensure adequate circulation to vital organs during physiological stress.
2. Inflammatory Response
The immune response thrives on inflammation. However, this comes with direct vascular consequences during illnesses.
When an elder is ill, peripheral resistance increases while the blood vessels become less active and non-compliant. Since vascular resistance largely determines blood pressure, narrowing of vessel walls drives a pressure increase. The inflammatory effect in older adults already experiencing endothelial dysfunction will be even more pronounced.
3. Redistribution of Blood Flow
The human body gets into survival mode when ill. During these episodes, the direction of blood flow goes toward critical organs such as the brain, heart, and kidneys.
In less critical regions like the skin, this circulatory redistribution occurs through vasoconstriction. Vessel constriction increases blood pressure and activates resistance to blood flow. This explains why people tend to experience high blood pressure and intense cold when ill.
4. Sympathetic Nervous System Activation
The sympathetic nervous system becomes more active during illness. It causes the pulse to beat faster, while the heart increasingly contracts. This system acts rapidly and can significantly elevate blood pressure, particularly in individuals already predisposed to hypertension.
Specific Conditions and Illnesses That Increase Blood Pressure
Virtually all illnesses contribute to varying spikes in blood pressure in some capacity. However, certain illnesses or conditions trigger a more significant increase in blood pressure than others.
Unlike other illnesses, paying special attention to elders with these can save their lives.
Since these specific health conditions are more likely to cause a serious heart condition, elders must inform their medical emergency response provider beforehand. This will help the monitoring unit determine the correct dispatch to send their way in an emergency.
These conditions will most likely produce noticeable increases in blood pressure:
- Respiratory infections: A seemingly harmless cold or flu can increase stress hormones and sympathetic activity, especially in elders.
- Bacterial infections: Infections from injuries or exposure to infected surfaces or humans intensify inflammation and vascular resistance.
- Dehydrating illnesses: They initially lower blood pressure before triggering compensatory increases.
- Chronic disease flare-ups: Kidney diseases and diabetes tend to disrupt fluid and pressure regulation.
Infections are the major drivers of blood pressure spikes in specific illnesses. Besides inflammation, they also contribute to stress responses in aging individuals.
How Medication Affects Blood Pressure During Illness
Did you know that medication can also raise blood pressure during illness? This realization is probably shocking because medication ought to be the solution and not the problem.
In reality, certain medications, especially over-the-counter drugs people use when sick, increase blood pressure by default. Unfortunately, most people overlook this aspect as a possible factor.
Although these types of medicines may be effective in some capacity, elders must be careful when taking them:
- Decongestants
- Medicines containing sodium
- Certain anti-inflammatory drugs
These medicines constrict blood vessels when taken. They may also increase fluid retention, which only exacerbates the ongoing physiological challenge during an illness.
