AI Detect Low Sugar Levels

AI in healthcare is strengthening its presence with new capabilities to diagnosis the health conditions of people with an acceptable level of accuracy. Recently we have shared post explains how does Google AI detect breast cancer better than radiologists.

And now, a new study came out in which researchers developed a new AI-based technique that can detect the low sugar levels from raw ECG signals using the wearable sensors without any fingerpicking test or taking the blood samples.

Currently, apart from giving the blood samples at diagnosis centers, diabetic people use to measure glucose using the needles at their home with repeated fingerpicks over the day. This is a painful process deterring patient compliance.

Check sugare levels

But now a new technique developed by researchers at the University of Warwick works with an 82% accuracy, could be the best option for invasive finger-prick testing with a needle, especially for kids who are afraid of needles fingerpicking.

How AI Detect Low Sugar Levels or Hypoglycemia?

The University of Warwick researchers examined how ECG readings changed during a hypoglycaemic event, when blood sugar levels fall below four millimoles per litre. And they then used the AI system to recognize low levels compared to normal readings. 

As per Dr Leandro Pecchia, from Warwick’s School of Engineering, the AI model has been trained to detect such hypoglycaemia via few ECG beats. This is possible as ECG can be detected in any circumstance, even while sleeping.

Dr. Leandro Pecchia with the new technology 

How AI is Trained to Detect Sugar Level in Humans?

The study is also explained how the AI was trained on the specific patterns of individual patients rather than on cohort data. This is because the ECG signals that correspond to hypoglycaemic events are different for each patient.

ECG checking sugar levels

The figure shows the output of the algorithms over time – the green line represents normal glucose levels, while the red line represents the low glucose levels.

However, this makes difficult, or almost impossible to develop a single AI algorithm that could be rolled out for all patients. However, this may restrict the technology to some degree but allow more tailored treatment of individual patients based on their personal ECG data.

This result is possible because the Warwick AI model is trained with each subject’s own data. Intersubjective differences are so significant, that training the system using cohort data would not give the same results. Likewise, personalized therapy based on our system could be more effective than current approaches.

However, more precise and magnitude of training data will help the AI model learn to detect with more variations while diagnosing such diseases. Getting healthcare training data is crucial for AI engineers to develop such models that can detect the various types of diseases among humans.

To avoid diabetes and keep your body fit, make sure to do some workouts and regular exercise and control your sugar intake. A high or low sugar levels both are dangerous for health and if not cured with precautions, it can become life-threatening diseases.

Why it is important for diabetes patients to check their glucose levels regularly?

Diabetes is a serious life-long condition that occurs when the amount of sugar in the blood is too high because the body can’t use it properly. Patients have to regularly monitor their glucose levels to prevent them from developing any potentially fatal complications.

why check glucose levels

Type 1 diabetes patients are often recommended to test their blood sugar at least four times a day. For type 2 patients, doctors advise testing twice a day. Blood glucose levels should be between the ranges of 3.5–5.5 mmol/L before meals and less than 8 mmol/L, two hours after meals.

What is Hypoglycemia and How it is Dangerous for you?

Hypoglycemia (when blood sugar drops below 4 mmol/L) can occasionally lead to patients falling into comas in severe cases. However, it most often can be treated through eating or drinking 15-20g of fast-acting carbohydrate, such 200 ml of Lucozade Energy Original.

hypoglycemia symptoms

Sufferers can tell they are experiencing a hypo when they suddenly feel tired, have difficulty concentrating or feel dizzy. Type 1 diabetes patients are more likely to experience a hypo, because of the medications they take, including insulin.

Hyperglycemia (when blood sugar is above 11.0 mmol/L two hours after a meal) can also have life-threatening complications. It happens when the body either has too little insulin, seen in type 1,or it can’t use its supply properly, most often in type 2.

In the short-term, it can lead to conditions including ketoacidosis – which causes ketones to be released into the body.  If left untreated, hyperglycemia can lead to long-term complications, such as impotence and amputations of limbs.

Regular exercise can help to lower blood sugar levels over time, and following a healthy diet and proper meal planning can also avoid dangerous spikes.

how ai in breast cancer

AI in healthcare is becoming more crucial with early detection of various diseases with better accuracy. Cancer is one the widespread deadly disease can be now detected through machine learning and AI-enabled automated machines.

Breast cancer is most common among women worldwide. However, more than 90% of women diagnosed with breast cancer at the earliest stage survive their disease for at least 5 years compared to around 15% for women diagnosed with the most advanced stage of the disease, which is now possible with AI.

Though, AI is already diagnosing breast cancer but owing to accuracy, the reliability among the doctors was less. But now Google has developed an AI system that can detect the early signs of breast cancer better than radiologists.

Research of Google Breast Cancer AI

In the research, the Google’s AI model called DeepMind AI was trained and tuned on a representative data set comprised of de-identified mammograms from more than 76,000 women in the U.K. and more than 15,000 women in the U.S.

AI in Breast Cancer diagnosis

The AI model is trained to see if it could learn to spot signs of breast cancer in the scans. The model was then evaluated on a separate de-identified data set of more than 25,000 women in the U.K. and over 3,000 women in the United States.

AI in cancer detection better than Radiologist

In this study, researchers conducted a test where Google’s AI system was pitted against six radiologists where the AI managed to outperform all six of them at accurately detecting breast cancer among these women at better accuracy.

Earlier, when a similar study is conducted in which the team first trained AI to scan X-ray images, then looked for signs of breast cancer by identifying changes in the breasts of the 28,000 women. They then checked the computer’s guesses against the women’s’ actual medical outcomes, reducing the reliability of such applications.

People Trust in AI in healthcare

But now, the accuracy level has improved and reduced false negatives by 9.4% and cut down false positives by 5.7% for women in the US. In the UK, where two radiologists typically double-check the results, the model cut down false negatives by 2.7% and reduced false positives by 1.2% make AI more reliable.

How Does AI Detect Breast Cancer?

Breast cancer diagnosis is done by oncologist’s human knowledge and intuition of what major risk factors might be, such as age, family history of breast and ovarian cancer, hormonal and reproductive factors, and breast density.

Google AI in breast cancer detection

While AI in breast cancer diagnosis, rather than manually identifying the patterns in a mammogram that drives future cancer, the MIT/MGH team trained a deep-learning model to deduce the patterns directly from the medical imaging data.

Video: How AI Model Improves Breast Cancer Detection on Mammograms

And using the information from more than 90,000 mammograms, the model detected patterns too subtle for the human eye to detect the cancer cells. The Google breast cancer AI algorithms are used to learn such patterns and predict.

You can check below an image showing the visualization of tumor growth and metastatic spread in breast cancer with screening to detect breast cancer early, before symptoms develop.

Actually, the demographics of the population studied by the authors are not well defined in the previous AI-based detection. As the performance of AI algorithms can be highly dependent on the population used in the training data sets.

And these training data sets are created by annotating the medical images of breast infected with cancer available in various formats like X-rays, CT Scan and MRI. A huge amount of such labeled data is used to train the AI algorithms.

There are many companies providing healthcare training data with annotated medical imaging to train the AI and ML models with accuracy.

And with the availability of such data, detection of various types of other common cancer through AI will become possible benefiting the humans saving their life from such maladies.
