Could you have a blood clot?

Your blood has one of the most important and complex jobs in your body. It flows continuously through your veins and arteries delivering nutrients and oxygen while overcoming bumps and lumps, twists and turns, all this with a fluctuating blood pressure. Sometimes, this whole commotion can lead to the formation of blood clots. Clotting can be healthy and normal - helping with wound healing - but it can also be dangerous when the blood clot forms in places where it's not needed. What is a blood clot? A blood clot is a cluster of blood that has changed from a…

What causes the feeling of pins and needles?

Have you ever felt like your arms, legs or feet have fallen asleep after being in a position for too long, followed by a tingling sensation, as if you were being pricked by tiny needles? Also known as paraesthesia, this prickly, burning, tingling, numb, itchy sensation is usually harmless. In in some cases, though, it can be a sign of something more serious. What causes the tingling? It usually happens if you lean or lay awkwardly on your arm or leg. This can put pressure on a nerve or reduce the blood supply to the area you’re resting on. It usually…

Under the spotlight: Cortisol

Think of cortisol as your body’s alarm system. It’s the main stress hormone which helps fuel your body’s fight or flight response in emergencies. Cortisol works with certain parts of the brain to help control your mood, motivation and fear responses. What does cortisol do? Triangle-shaped hormones called the adrenal glands make cortisol. Almost every cell in your body has receptors for cortisol, so this means that cortisol is involved in different actions in the body. These include: Managing how your body uses carbohydrates, fats, and proteins. Acting as an anti-inflammatory when needed. Regulating your blood pressure. Increasing your blood sugar (glucose).

Supercharge your diet by pairing these foods

Wine and chocolate, burgers and fries…we’re all familiar with pairing food for taste (whether healthy or not). Now here’s something you probably haven’t tried: pairing food for their nutritional value. Combining certain foods may be more helpful than eating them separately as some nutrients work better side by side. Food synergy Food synergy means combining two nutrient-rich foods in one dish to maximise the dietary impact. Certain components in foods and drinks (like minerals, vitamins and phytochemicals, fibre, and fats) interact with each other to boost health benefits. Sometimes, those benefits may include weight loss! Research from The American Journal…

What is cholesterol?

Cholesterol is a fatty substance produced naturally by your liver and is used for many different things in your body. Cholesterol is one of the most important contributing risk factors leading to the development of heart disease and stroke. Others include age, gender and genes. What is cholesterol, exactly? Have you heard your doctor talking about LDL and HDL cholesterol? LDL (Low density lipoprotein) is known as the ‘bad’ cholesterol because it contributes to heart disease by ‘sticking’ to and narrowing the arteries supplying blood to your heart. HDL (High density lipoprotein) cholesterol is known as the ‘good’ cholesterol because…

Is dad having a stroke? What do I do?

You’re having your usual Sunday afternoon chat with dad, he’s laughing at one of your lame jokes – and suddenly stops. He says something, but you can’t hear what it is. His speech is slurred and his infectious smile is suddenly gone. Is he having a stroke? We hope that you never have to experience this. If you do, though, we want to be sure you’re prepared. What is happening? When someone has a stroke, the blood supply to their brain gets cut off; blood carries nutrients and oxygen to the brain and without these, cells become damaged and die.…
