How do I know if I have a weak heart?

Typical signs of heart failure include: Breathlessness or Shortness of Breath (Dyspnea) When the heart begins to fail, blood backs up in the veins attempting to carry oxygenated blood from the lungs to the heart. As fluid pools in the lungs, it interferes with normal breathing.

Heart failure is a condition in which the heart fails to function properly. The terms "heart failure" and "congestive heart failure (CHF)" don't mean that the heart has actually "failed" or stopped but mean one or more chambers of the heart "fail" to keep up with the volume of blood flowing through them. Heart failure is brought on by a variety of underlying diseases and health problems. Your condition may involve the left side, the right side or both sides of the heart. Each side has two chambers:

An atrium or upper chamber

A ventricle or lower chamber

Any one of these four chambers may not be able to keep up with the volume of blood flowing through it.

Two types of heart dysfunction can lead to heart failure, including:

Systolic Heart Failure This is the most common cause of heart failure and occurs when the heart is weak and enlarged. The muscle of the left ventricle loses some of its ability to contract or shorten. In turn, it may not have the muscle power to pump the amount of oxygenated and nutrient-filled blood the body needs. This is the most common cause of heart failure and occurs when the heart is weak and enlarged. The muscle of the left ventricle loses some of its ability to contract or shorten. In turn, it may not have the muscle power to pump the amount of oxygenated and nutrient-filled blood the body needs. Diastolic Failure The muscle becomes stiff and loses some of its ability to relax. As a result, the affected chamber has trouble filling with blood during the rest period that occurs between each heartbeat. Often the walls of the heart thicken, and the size of the left chamber may be normal or reduced. The left side of the heart is crucial for normal heart function and is usually where heart failure begins. The left atrium receives oxygen-rich blood from the lungs and pumps it into the left ventricle, the heart's largest and strongest pump, which is responsible for supplying blood to the body. After it has circulated through the body, blood returns to the right atrium and then travels to the right ventricle, which pumps it into the lungs to be replenished with oxygen. When the right side loses pumping power, blood can back up in the veins attempting to return blood to the heart. Right heart failure may occur alone but is usually a result of left-sided failure. When the left ventricle fails, fluid backs up in the lungs. In turn, pressure from excess fluid can damage the heart's right side as it works to pump blood into the lungs. Heart failure usually is a chronic, or long-term, condition that gradually gets worse. By the time most people notice and see a doctor about their symptoms, the heart has been "failing," little by little, for a long time. This is a good reason to have regular health checkups. During a routine physical examination, your doctor may detect signs of heart failure long before you experience symptoms. Heart failure rarely occurs suddenly except after a major heart attack, severe heart valve problem or period of seriously high blood pressure.

webmd.com - Can Supplements Improve Your Energy? - WebMD

Vitamins and minerals are substances your body needs to build energy, help you stay healthy, and function properly. To naturally maintain your day-to-day energy levels, it’s best to get your vitamins from your food. But if you’re not able to meet your daily requirement through food alone, you may reach for supplements to make up the difference. But do supplements really boost energy? Some may make a difference, but others may need more research to back up the energy-boosting claims. Vitamin B12 This is a type of nutrient that keeps you blood and nerve cells healthy. It also helps your body make genetic material (DNA). It’s naturally found in animal-based foods only. So, if you’re a vegan or vegetarian, you may not be getting enough. This can also happen if you’re pregnant, anemic, or have trouble absorbing it. If you lack vitamin B12, you may feel tired and weak. But supplements may not be a quick fix. Research shows that there isn’t enough evidence to prove they boost energy. On average, an adult only needs 2.4 micrograms (mcg) of B12 per day. But your body stores up to 2,000 times your daily requirement, so it usually takes several years for deficiency to show up. Your doctor can do a blood test to see if you’re really deficient. Supplements may contain much higher doses than the minimum requirement, but they’re still relatively safe. But they may interact with certain prescription or over-the-counter drugs. Check with your doctor before you take them. Vitamin B12 supplements are available over the counter in pill form that contain just the B vitamins or as part of a multivitamin. They’re also available as prescription shots or nasal gel.
