Is there a link between Type 2 diabetes and anxiety?
Living with Type 2 diabetes isn't always easy. Find out how to reduce anxiety associated with the condition.
Everyone feels tired sometimes, but fatigue, or feeling extremely tired, is common in Type 2 diabetes.
Lots of different things can cause it. Sometimes, it is related to blood glucose levels or other symptoms of the condition. It could be a medication side effect, or it might be a sign of a complication.
Whatever the cause, fatigue can have a huge impact on your quality of life. It can get in the way of work and family commitments and stop you from doing the things you love.
The good news is that there are things you can do to manage fatigue.
Fatigue is a feeling of exhaustion and lethargy that can sometimes be overwhelming.
People say they are tired all the time, but anyone who has experienced fatigue knows it is much more than that. When someone is tired, they will usually feel better after they have rested, but fatigue might not go away after a nap or a good night’s sleep.
Fatigue is common in lots of long-term healthcare conditions, including diabetes, multiple sclerosis and inflammatory bowel disease. Some people describe it as feeling weighted down, like walking through quicksand or like having the flu.
Fatigue is very common in Type 2 diabetes. A study published by the American Diabetes Association found that it affected 61 per cent of newly diagnosed people.
There are lots of different reasons for this:
When we eat carbohydrates, the digestive system breaks them down into sugar. Experts call this sugar glucose, and it is the body’s main source of energy. It travels to every part of the body in the blood.
Insulin is a hormone. It makes sure there is never too much, or too little glucose in the blood, so that the body has the energy it needs. But when people develop Type 2 diabetes, they stop making insulin properly and the regulation system breaks down.
Hypoglycaemia means that there is not enough sugar in the blood. Sometimes, people call this “having a hypo”. Fatigue is a common symptom of low blood sugar.
It is different for everyone, but other symptoms might include:
If you think you might be having a hypo, you should treat it right away. Low blood sugar levels can be very dangerous.
Lots of the common symptoms of Type 2 diabetes can contribute to feelings of tiredness and fatigue.
Things like needing to urinate a lot, feeling really thirsty, and feeling really hungry can all make you feel tired.
They can also interrupt sleep patterns, adding to fatigue. People with Type 2 diabetes might have to get up in the night to use the toilet or get a drink, for example. Or sometimes, pain or discomfort in the feet might stop people from getting to sleep or wake them up.
People with Type 2 diabetes are more likely to experience anxiety and depression than the general population.
Poor mental health and wellbeing can also add to fatigue. It can impact on how well someone is able to manage their blood sugar levels. It can also change sleep patterns and leave people feeling low.
People with Type 2 diabetes often take several different medications. Some of them can contribute to feelings of extreme tiredness.
Over time, high blood sugar levels can damage the blood vessels and organs. This can lead to complications. Fatigue can be a symptom of complications such as:
It is important to remember that uncontrolled blood sugar levels cause these complications, not Type 2 diabetes itself. You can help avoid complications by managing your condition through good lifestyle choices.
Fatigue can have a huge impact on your life, but there are things you can do to manage the feeling.
If low blood sugar was the cause of the problem, it should usually get better after treatment. According to Diabetes UK, you should eat or drink 15-20g of fast-acting carbohydrate as soon as you realise you have low blood sugar. That might be:
Getting enough sleep is the first step to managing fatigue. Most people need between six and nine hours of sleep.
Of course, this is not always easy, especially when the symptoms of Type 2 diabetes get in the way.
