Causes of Migraines

migraines
Migraines can be defined as a serious headache that is accompanied with a range of symptoms such as visual disturbances, aura, nausea, vomiting and numbness. Women are three times more likely to experience a migraine than men, and it is thought that hormones have a role to play in this.

Pre-menstrual and expectant women are more likely to suffer from migraines due to increased levels of hormones in the blood. In fact, many women will experience a migraine for the first time ever whilst pregnant, with symptoms disappearing altogether once they have delivered.

Migraine Types

Migraines fall into one of two categories, classical or common. A classical migraine is one in which there are visual disturbances and aura for the patient, whereas a common migraine presents itself without visual problems.

Some patients only ever suffer from one type of migraine, whilst others can suffer both types. Stress is usually an indicator in the severity of the attack itself, which can last anything from a few hours to a few days, several times a week.

Stages of a Migraine

There are five definite stages for the onset of a migraine, although it is not necessary that a person will experience all of them. These are:
  1. Pre-headache or prodromal stage – this is a general change in a person's mood and behaviour before a migraine starts and can include aches and pains and a change in appetite. This stage can start days before a migraine.
  2. Aura – about 17% of patients complain about visual disturbances that include flashing lights, blurred vision, blindness and blind spots. These can last anywhere up to an hour.
  3. Headache stage – this is when the actual migraine takes hold and means throbbing and severe pain in one side of the head, often with nausea, vomiting and an aversion to bright lights and noise. The best solution is to lie down in a dark room and sleep it off. This stage can last up to three days.
  4. Resolution stage – this is when the pain subsides and gradually all symptoms fade away. Sleep usually helps to speed up this stage, and some people can even stop having a migraine as soon as they have been sick.
  5. Recovery or postdromal stage – this is when the migraine has gone, but can leave a person feeling drained and exhausted, or even elated in some circumstances.

Triggers for a Migraine

Migraine can be triggered by many things, the most common being food and stress. Other triggers can include the following:
  • lack of sleep
  • skipping meals
  • cheese, chocolate, citrus food and caffeine
  • shock
  • depression
  • poor posture
  • dehydration
  • certain medication
  • flickering screens and flashing lights
  • stuffy atmosphere

Treatment for Migraine

Treatment for migraine means identifying and avoiding the triggers, and then treatment itself in the form of pain killers (such as paracetamol and aspirin) and anti-inflammatory tablets (like ibuprofen and diclofenac).

The key to successful treatment is taking the medicine as soon as the symptoms start – taking it when the pain is severe will have little effect on the migraine. Anti-sickness drugs are often given if you experience nausea and vomiting with your migraine.

One of the most overlooked of all treatments is drinking water. Migraines are made worse by dehydration and consuming copious amounts of water can delay or prevent the onset of a migraine.

Migraines which do not respond to conventional treatments need to be investigated further by a specialist.

Safeguard the Achilles

One of the most painful tendon injuries is Achilles. But there are also ways to avoid these injuries. Here are some of them: You’ll feel a burning and piercing in the tendon above your heel and it can even make a crackling sound when you move it. Any higher up your calf and it’s more likely that you’ve strained or pulled a muscle. Rupturing your Achilles tendon is a exceptionally painful experience and you’ll know when you’ve done it. Your Achilles tendon connects your calf muscles to your heel bone and is made of thousands of individual fibers of collagen. Restricted blood flow to this area slows repair and pain will worsen if you keep training . Four important factors in healing the Achilles are: rest, ice, compression and elevation. If your tendon is harmed take a break from all weight bearing sport (except swimming) for at least 2 weeks. You can recover from mild injury in a couple of weeks but a severe one can take 5 months. In order to prevent Achilles injury in

Diabetes Food Pyramid

This diabetic food pyramid functions in a similar way to the regular food pyramid. One of the main differences is that the diabetic food pyramid focuses on limiting sugar intake . Diabetes is a disease that prohibits people from eating sugar at the same levels that they used to. This does not mean that all diabetics have to avoid sugar like vampires avoid the sun! Some people have mild cases that enable them to eat sugar once in a while. Others have to avoid it at all costs. The diabetic food pyramid is a lifesaver to many people. Just by looking at the pyramid they can tell which foods to eat and which ones not to. It also suggests serving sizes and suggestions for planning whole meals. The diabetic food pyramid has six categories of food groups. At the bottom the main group is grains, starchy vegetables, and beans. The second grouping on the diabetic food pyramid includes vegetables and fruits . The third includes diary products, meats and other sources of protein. At the t

Causes of Easy Bruising: Reasons Why People Bruise Easily

Bruising , a reddish or purple discoloration under the skin, most often results from trauma to the small blood vessels, called capillaries, but can also occur spontaneously. How and Why Bruises Occur Blood leaks out of the capillaries and accumulates under the skin, gradually absorbing over several days. Bruising most often occurs because people run into objects or experience other trauma. Most bruising is easily explained, but frequent bruising that occurs without obvious cause needs prompt investigation, since several serious diseases can cause bruising. In general, women bruise more easily than men. How Aging Increases the Risk of Easy Bruising Bruising increases as people age for several reasons. Skin thins as people age and the capillaries become more fragile. The layer of fat that cushions blood vessels and protects them from injury becomes thinner as well. Older people often take medications and supplements that thin the blood and contribute to easy bruising. Visi
