I am type 1.5 LADA …simply put it means …type one produce no insulin…type 2 produce little insulin…type 1.5 produces insulin but the body also produces antibodies that attack the insulin as intruder and it kills them. also type 1 comes on fast but type1.5 comes on slow. hope that helps

I was just diagnosed 2 months ago but never was told what type I am but I have to take 4 shots of insulin a day and am not taking a pill so I figured I must be type 1. After reading about the different types it sounds like I'm type 1.5 since I'm 41 yrs. old, thanks for the info.

There are many types of diabetes with the most common ones being Type 1, Type 2, and Gestational Diabetes.

Type 1.5 is Type 1 that developes later in life caused either by the failure of one's Beta Cells in the pancreas to produce insulin, or the destruction of these same cells by one's body.

It is also known as "Slow Onset Diabetes."

Here are the other types of diabetes which are known by names , or what causes them instead of a name \ number combination:

(Other Types of Diabetes)

A number of other types of diabetes exist. A person may exhibit characteristics of more than one type. For example, in latent autoimmune diabetes in adults (LADA), also called type 1.5 diabetes or double diabetes, people show signs of both type 1 and type 2 diabetes.

Other types of diabetes include those caused by

•genetic defects of the beta cell-the part of the pancreas that makes insulin-such as maturity-onset diabetes of the young (MODY) or neonatal diabetes mellitus (NDM)
•genetic defects in insulin action, resulting in the body's inability to control blood glucose levels, as seen in leprechaunism and the Rabson-Mendenhall syndrome
•diseases of the pancreas or conditions that damage the pancreas, such as pancreatitis and cystic fibrosis
•excess amounts of certain hormones resulting from some medical conditions-such as cortisol in Cushing's syndrome-that work against the action of insulin
•medications that reduce insulin action, such as glucocorticoids, or chemicals that destroy beta cells
•infections, such as congenital rubella and cytomegalovirus
•rare immune-mediated disorders, such as stiff-man syndrome, an autoimmune disease of the central nervous system
•genetic syndromes associated with diabetes, such as Down syndrome and Prader-Willi syndrome

Latent Autoimmune Diabetes in Adults (LADA)
People who have LADA show signs of both type 1 and type 2 diabetes. Diagnosis usually occurs after age 30. Researchers estimate that as many as 10 percent of people diagnosed with type 2 diabetes have LADA. Some experts believe that LADA is a slowly developing kind of type 1 diabetes because patients have antibodies against the insulin-producing beta cells of the pancreas.

Most people with LADA still produce their own insulin when first diagnosed, like those with type 2 diabetes. In the early stages of the disease, people with LADA do not require insulin injections. Instead, they control their blood glucose levels with meal planning, physical activity, and oral diabetes medications. However, several years after diagnosis, people with LADA must take insulin to control blood glucose levels. As LADA progresses, the beta cells of the pancreas may no longer make insulin because the body's immune system has attacked and destroyed them, as in type 1 diabetes.

Diabetes Caused by Genetic Defects of the Beta Cell
Genetic defects of the beta cell cause several forms of diabetes. For example, monogenic forms of diabetes result from mutations, or changes, in a single gene. In most cases of monogenic diabetes, the gene mutation is inherited. In the remaining cases, the gene mutation develops spontaneously. Most mutations in monogenic diabetes reduce the body's ability to produce insulin. Genetic testing can diagnose most forms of monogenic diabetes.

NDM and MODY are the two main forms of monogenic diabetes. NDM is a form of diabetes that occurs in the first 6 months of life. Infants with NDM do not produce enough insulin, leading to an increase in blood glucose. NDM can be mistaken for the much more common type 1 diabetes, but type 1 diabetes usually occurs after the first 6 months of life. More information about the two types of NDM, permanent neonatal diabetes and transient neonatal diabetes mellitus, is provided in the fact sheet Monogenic Forms of Diabetes, available online from the NDIC at For printed copies of the fact sheet, call the NDIC at 1-800-860-8747.

MODY usually first occurs during adolescence or early adulthood. However, MODY sometimes remains undiagnosed until later in life. A number of different gene mutations have been shown to cause MODY, all of which limit the pancreas' ability to produce insulin. This process leads to the high blood glucose levels characteristic of diabetes. More information about specific types of MODY is provided in the fact sheet Monogenic Forms of Diabetes.

Diabetes Caused by Genetic Defects in Insulin Action
A number of types of diabetes result from genetic defects in insulin action. Changes to the insulin receptor may cause mild hyperglycemia-high blood glucose-or severe diabetes. Symptoms may include acanthosis nigricans, a skin condition characterized by darkened skin patches, and, in women, enlarged and cystic ovaries plus virilization and the development of masculine characteristics such as excess facial hair. Two syndromes in children, leprechaunism and the Rabson-Mendenhall syndrome, cause extreme insulin resistance.

Diabetes Caused by Diseases of the Pancreas
Injuries to the pancreas from trauma or disease can cause diabetes. This category includes pancreatitis, infection, and cancer of the pancreas. Cystic fibrosis and hemochromatosis can also damage the pancreas enough to cause diabetes.

Diabetes Caused by Endocrinopathies
Excess amounts of certain hormones that work against the action of insulin can cause diabetes. These hormones and their related conditions include growth hormone in acromegaly, cortisol in Cushing's syndrome, glucagon in glucagonoma, and epinephrine in pheochromocytoma.

Diabetes Caused by Medications or Chemicals
A number of medications and chemicals can interfere with insulin secretion, leading to diabetes in people with insulin resistance. These medications and chemicals include pentamidine, nicotinic acid, glucocorticoids, thyroid hormone, phenytoin (Dilantin), and Vacor, a rat poison.

Diabetes Caused by Infections
Several infections are associated with the occurrence of diabetes, including congenital rubella, coxsackievirus B, cytomegalovirus, adenovirus, and mumps.

Rare Immune-mediated Types of Diabetes
Some immune-mediated disorders are associated with diabetes. About one-third of people with stiff-man syndrome develop diabetes. In other autoimmune diseases, such as systemic lupus erythematosus, patients may have anti-insulin receptor antibodies that cause diabetes by interfering with the binding of insulin to body tissues.

I hope that I didn't bore you!

With so many types and causes of diabetes no wonder the search for a cure is even more complicated.
Thanks for the information Mays.

WOW, I had no idea that there was so many different types and causes.Thank you so much for the information and no you didn't bore me.

this was very instresting. i seriously have learned alot by reading your article. i like to learn about things that have to do with diabetes that didn't know about before. i take it seriously that i have diabeties.always intrested to learn things about it i din't know before. thank you for sharing this information on here.

Well I go to a diabetes management and support group here in Las Vegas, and Chris talks about a type 3 diabetic all the time. He calls himself a type 3. His loved one, his wife Theresa is a type 1 and he cares for her, that makes him a type 3. So when my Jem was living, I was both a type 2 and a type 3, LoL!

There are several recognized "types" but there is also a likely continuum from Prue- all the way to full blown, insulin requiring types…

Type 1.5 can be LADA Latent Autoimmune Diabetes of Adults or MODY Mature Onset Diabetes of Youth. You can do web search on each and learn about them including symptoms, tests, and diagnostiac criteria
